When trying to choose which paper I was going to report on, I initially was looking for articles that had to either entirely or more–or–less deal with a
topic that we covered in class; because of this, I was going to read the experiment that dealt with object permanence. However, after reading a small
portion of that experiment, it couldn't really grasp my attention, so I basically just went through the other articles looking for the titles that caught my
attention the most. After looking through all of the articles, it came down to the articles about action experience and joint engagement. Because I was
torn between the two, I read a little bit – mostly the introduction – of both reports, and I could easily tell that this report, the one on joint engagement,
would interest me more just because I could comprehend the study better and it just overall seemed much more intriguing when it comes to child
development. To say the least, I am glad I chose this article over the other one because I found myself really engaged in what the study had to offer. I
was very interested in the study and the overall experiment that I even found myself asking my own questions. Article Summary Each response should

Results
The solid water was the control variable in the experiment and the investigators compared values that resulted from irradiation of the solid water
with each bolus' average Dmax. Table 1 recorded the ratios that resulted from these values. ANOVA calculations from the values shown in Table 1
resulted in an F value of 762.65 and a P value of less than 0.0001. The investigator compared the results between each individual group with a Tukey
HSD test. When compared to one another, each sample resulted in a P value less than 0.01.

3. Hypothesis and Research Question Essay example
Research questions are formulated in a study to inquire about variables, both independent and dependent variables, and the relationship between them.
Research questions are categorized into two, that is, qualitative and quantitative research questions. Qualitative questions are used in qualitative
research like case studies, surveys and action research where the approach is non–numerical and analyses special phenomena that occur in nature.
Quantitative research on the other hand is more of a systematic approach with measurable numerical quantities that go through analysis to prove a
hypothesis. Finally, the research hypothesis is either approved or disapproved with regards to the results of the analysis (Laureate Online Education B.V.

It must be logical, and provide a concrete base for any differences between the variables. It must also be simple and clear.
A hypothesis can state the following: there exists a positive relationship between employee performance and flexible working hours. Whereas a
research question could generally be: do flexible working hours affect workers productivity? You can clearly see that the hypothesis states clearly and
it is more specific in its prediction unlike the research question (eNotes.com, Inc 2011).
Hypothesis is typically used in quantitative research only. Moreover, when a question poses an inquiry on the relationship between two variables, a
hypothesis is a statement declarative in nature of the relationship between different variables (Pajares 2007). A researcher chooses whether to use a
question or a hypothesis depending on the purpose of the research, its objectives, the methodology for the research and the preference of the audience
to receive the research. A researcher must be able to interpret the final outcome with reference to the research questions or the hypothesis used (Pajares
2007). A research requires a minimum of two hypotheses namely a null and an alternative hypothesis.
So, somebody can make a certain observation and come up with a hypothesis about how and why a phenomenon occurs the way it is. Hypothesis could

The scientific method is an endless cycle of logical and rational order of steps that consists of observation, regularity, theory, prediction, and testing
(Trefil & Hanzen, 2013). The scientific method is a way for individuals to ask and answer scientific questions by making observations and conducting
experiments. The scientific method is a process used to ensure that the experiments conducted can provide a good answer or solution to a specific
question. The steps of the scientific method include: ask a question, gather information and make observations, guess the answer, conduct experiments
and test the hypothesis, analyze the results of the tests, and come to a conclusion.

Brief Introduction:
AJ Davis is a department store chain, which has many credit customers and want to find out more information about these customers. AJ Davis has
complied a sample of 50 credit customers with data selected in the following variables: Location, Income (in $1,000's), Size (Number of people living
in the household), Years (number of years the customer has lived in the current location), and Credit Balance (customers current credit card balance on
the store's credit car, in $).

* My calculated test statistic of –2.07 falls in the rejection region of z < –0.1645, therefore, I would reject the null hypothesis and say there is
sufficient evidence to indicate u<50 or $50,000.
b. The true population proportion of customers who live in an urban area exceeds 40%
* 22 of the 50 surveyed live in the Urban area, which is 44% or 0.44, this is the point estimate for p.
* Therefore my hypothesis would be * Ho: = 0.40 vs. Ha: p>0.40
* In order to conduct the large sample z–test, we first need to verify that the sample size is large enough. * nPo= 50(0.40) = 20 and 50 (1–0.44) = 30,
both are larger than 15, so we can conclude that sample size is large enough to apply the large sample z test.
* Z= (0.44 – 0.400)/ 0.69282= 0.58 where s phat= sqrt (((0.40) (0.60))/50= 0.069282
* This is a one tailed (upper or right since HA has ">"). Our rejection regions would be z > 1.645.
* 0.58 is not greater than 1.645 (and is not in the rejection regions) so we would not Reject the Ho.

Week 1:
DQ1: What are the differences between descriptive and inferential statistics?
According to Bennett (2009), the biggest difference between descriptive and inferential statistics is that descriptive statistics "deals with describing raw
data in the form of graphics and sample of statistics" and inferential statistics "deals with estimating population parameters from sample data." This
means that inferential statistics would be an estimate because the data would be estimated from sample data rather than using specific data whereas
descriptive statistics would be more accurate. An example of descriptive statistics would be trying to find an average of something such as a G.P.A. or
your overall grade in a class. ... Show more content on Helpwriting.net ...
We come up with the number 7. 7 would be the mean in this case.
"The median is the middle value of the data set. To find a median we arrange the values in ascending (or descending) order, repeating data values
that appear more than once. If the number of values is odd, there is exactly one value in the middle of the list, and this value is the median. If the
number of values is even, there are two values in the middle of the list, and the median is the number that lies halfway between them. For an example
the list 3, 4, 6, 6, 10. The median number is 6 because 6 is the middle number in the list." (Bennett, Briggs, & Triola, 2009, p. 146).
"The mode is the most common value or group of values in a data set. For an example the mode in the number set 3, 4, 6, 6, 10 is 6 because this value
occurs twice in the data set."(Bennett, Briggs, & Triola, 2009, p. 146).
We would use mean, median and mode in healthcare to find the average of many things such as how effective a new medication would be on the
average population. Or how far into a new treatment patients start seeing results or improvements. Bennett, J.O., Briggs, W.L., & Triola, M.F.

10. Implications Of The El Greco Fallacy : Perceptions And...
The research conducted in the "top–down" effects in perception research was guided by the El Greco fallacy. Here, it is brought to the attention of
findings that distortions must have any alternative explanation besides a literal perceptual distortion. Researchers applied this theory because of the
fact that distortions must cancel each other out, since the means of reproduction should be distorted as was the stimulus being reproduced. In their
research, authors asked if higher–level states such as moods, action capabilities, and knowledge are truly effects on perception, or if subjects reflect
influences on memory or bias. The key question attempting to be answered here is, what determines how things look? After experiment 1 results
confirm that holding a rod decreases subjects' perception of aperture width estimates, in experiment 2 researchers ask if this confirmation reflect literal
perceptual compression of the apertures. Experiment 3 asks what explains aperture–compression effects. Researchers hypothesize that the
aperture–width effects should disappear once the subjects think the rod is being held for a purpose other than for "balance". For experiment 4,
researchers ask if reflecting on unethical deeds from subject's past will estimate a low brightness of room. The question that guided the research in
experiment 5, which applied the El Greco fallacy, is, is the effect of ethical reports on lightness judgments actually perceptual? The hypotheses were

11. A Research Study On The Null And Alternative Hypothesis
There are a variety of topics that are interesting in life. This interest may then become a point of inquisition, where an individual may formulate a
relationship between two variables, which may or may not influence each other. Next, a hypothesis is formed and tested. In this same manner, a school
educator was interested in determining the potential relationship between grade point average (GPA) and IQ scores among ninth graders. The educator
random sampled 30 ninth graders, ages 14 years old and administered the Wechsler Intelligence Scale for Children–Fourth Edition (WISC–IV). This
writer will be expanding further on this topic and will formulate the null and alternative hypothesis, describe the four scales of measurement, describe
whether if there is a correlation significant (positive, negative, or no correlation) enough between both variables, describe the strength of the
relationship, describe what the results reveals about the hypothesis, and what conclusions can be drawn from the results.
Null and alternative hypothesis The null hypothesis would reflect as if there is no difference between both variables (Malec & Newman, 2013). The
null hypothesis would indicate that there is no relationship between GPA and IQ. The alternative hypothesis would indicate another option, which is
contrary to the null and may or may not be directional (Malec & Newman, 2013). The alternative hypothesis would be, that there is a relationship
between GPA and IQ. This writer agrees with

There will be no formulated statements from non–parametric analysis in regard to the information that is presented by the researcher. The ANOVA,
(analysis of variation) is a commomlly used method of non–parametric. The researcher does an analysis with the ANOVA to see if there is a
differentation among groups, and if the mean of them are the same. With anull hypothesis the ANOVA will determine if the information that has been
presented has the same means, while with the alternative hypothesis it will determine if the information has defferent means. CTU Online, (2013)

Importance of Biostatistics and a Critique
Biostatistics is an integral component of numerous developments particularly in technology and modern medicine today. With biostatistics, we can
gather data, analyze it, create a hypothesis, test its validity and make a conclusion. This is essential because if we can make an inference from a
sample that represents a large population, not only we are able to save time, cost and effort but we are able to arrive to a conclusion that could help us
develop alternative treatments or tools in the future. For instance, in concept practice 4, we assessed the usefulness of the iPhone rhinoplasty app for

A mean plot "provides a visual comparison of means and standard deviations" which includes centers and spreads (Daddysman, Multiple–Sample
Studies: Summaries and Estimation, 2017). A box plot is a "graphical representation of the five–number summary...the minimum, 1st quartile range,
median, 3rd quartile range, and the maximum" (Daddysman, One–Sample Studies: Summaries, 2017). And a scatterplot "graphically represents
two–variable relationships...describing its form, direction and strength" (Daddysman, Simple Linear Regression: Inference and Reporting, 2017). For
instance, based on our graph in concept practice 9, we've learned the relationship between our slope and our two variables – number of logins and the
HBA1c results. As the number of logins increase by 1 unit, the hbA1c results decrease by .0067. Each graphical summary is important in understanding
and comparing two variables to describe gathered data, determining differences and arriving to a conclusion.
Biostatistics also taught us how to recognize study designs and write a summary and critique. This is helpful because it identifies positive and negative
aspects of the study and an opportunity for other people to replicate the study and improve it. For instance, on the 26th of June 2017, I submitted a

14. The Theory Of Psychology And Psychology
The unified approach refers to a common basis within a field in which all agree. Historically psychology has tried to establish a unified approach using
structuralism. Structuralism explores the structure of the human mind by analysing consciousness into component parts. Psychologists later excluded
structuralism in exchange towards functionalism (Magnavita, 2005). Psychology is the scientific study of behaviour and the mind. While behaviour
can be directly observed for example through actions and responses, the mind cannot directly be seen for example thoughts. Psychology trusts upon
the feedback of participants through gathering data and then analysing to conclude. All research occurs while adhering to the BPS code of ethics.
There are a variety of ways to study the mind and behaviour and similarly there are a variety of approaches to psychology. Unlike chemistry and
physics, which adopt a singular purpose and agreed consensus. Psychology can be complex and therefore cannot rely solely on one approach (
Gleitman, Reisberg & Gross, 2010) 2. The psychodynamic approach was first stimulated by Sigmund Freud in 1896. He believed that not all thoughts
are conscious and all behavior has a cause. He argued that the majority of behaviours are often innate or derive from early childhood experiences. He
also argued that consciousness is influenced by subconscious aspirations and thoughts. The approach emphasises the association between subconscious
efforts and the subsequent

Building blocks learning organizations should be skilled in are 1) Systematic problem–solving: A wide range of organizations used this method
worldwide since it depends on the scientific method. It starts with making an observation, gathering data/information regarding that observation to form
a hypothesis. Ahypothesis is a proposed description of the observation made on the available evidence (in the form of data). One of the pioneers of
the quality control, W Edward Deming calls it "Plan, Do, Check, Act" cycle while others refer as "hypothesis–generating, hypothesis testing"
techniques. This method outlaw's focus on guess work or intuitive mode of problem–solving considering self–made assumptions. Although the
scientific method is time taking than intuitive approach. The former leads to a high–quality solution and support effective problem–solving. One can
also derive this as the fact–based management since it first collects data, analyze it, draws conclusions, and decides whether to proceed to the
succeeding level or reject the hypothesis or modify to further continue. Various simple statistical tools, for instance, histogram, Pareto charts,
correlations, cause and effect diagram assist in data analysis to draw results. The problem–solving method is a beneficial method when it comes to

The purpose or the significance of the experiment was to see if brine shrimp can survive in different salinities of saltwater. The experimental

shrimp when the salinity level (in grams) increased. It was in Figure 1 and it shown that the rates had higher numbers (increased survival rates) and
the lower salinities had lower survival rates. The raw data also had shown that higher numbers were in the higher salinities rather than in the lower
salinities. The salt had an effect on the Brine Shrimp, is because the more the more salt they had (being a saltwater species) would lead to more
surviving unlike a lower salinity which did not have enough salt to support the DV (the Brine Shrimp). In the literature review, we stated that others
have also shown that the higher the salinity, the higher chances of the brine shrimp surviving in the saltwater. We were uncertain about the brine

18. Self Control Theory : A General Theory Of Crime
Self–control theory hypothesizes that self–discipline explains a variance in the extent to which people are susceptible to specific urges, whether
committing criminal or non–criminal actions. Travis Hirschi and Michael Gottfredson gave rise to self–control theory in their book named A General
Theory of Crime. Because its creators define the self–control theory as a "general theory of crime", to them it is believed that this theory can be
implemented to multiple behaviors where a person is not capable to resist desires, which allow for a quick self–gratification. Not only this, but
Gottfredson and Hirschi also trust that the self–control theory describes the flexibility of crime; because of this, it is appropriate to assume that
criminals are also expected to partake in other dangerous behaviors seen as innocent by the law (Kubrin, Stucky, and Krohn 187).
Self–control theory operates under the assumption that willpower is developed early on in childhood and from thereafter it is relatively stable
throughout the remainder of that individual's life. Hirschi and Gottfredson state that low–self control can be determined by an individual's propensity
to have behaviors revolving around being "impulsive, insensitive, physical, risk–taking, short–sighted, and non–verbal" while also having a "here and
now" attitude towards situations (Kubrin, Stucky, and Krohn 186–187).

The goal of this study was to measure interpersonal attraction as a means of determining whether or not there was a social stigma associated with
different loneliness states and race. The dependent variable in this study was the interpersonal attraction rating while the loneliness state and race were
the independent variables. Both race and loneliness state had the potential to impact the interpersonal attraction rating of the characters. According to
the results from this study, the null hypothesis had to be rejected. There was a significant difference between lonely and nonlonely states. The first
alternate hypothesis predicted that lonely people would exhibit less interpersonal attraction than nonlonely people. This could be accepted. However, the
second alternate hypothesis could not be accepted because there was no significant difference between Hispanic and White conditions, despite that the
hypothesis predicted that Hispanics would be judged more harshly. The third and fourth alternate hypotheses, which predicted that the Hispanic
condition would be less likeable in both loneliness states, could not be accepted based on the data of this study. By accepting the first alternate
hypothesis, the researchers uphold the findings of Lau and Gruen (1992). Their data indicated that there was a greater social stigma associated with
lonely people than nonlonely people. While Lau and Gruen (1992) found that the stigma interacted with gender, lonely women were judged more

An experiment was performed to examine the age at which infants recognize certain outcomes as impossible. Five–month old infants were tested in the
procedure depicted in Figure 1. 3a. According to Figure 1, the first step in the experimental procedure is that two identical objects are to be placed into
a case or box, these objects are primarily toys that would capture an infant's attention. The infant would be roughly 5–months old, and the next step of
the experimental would consist that the screen that is hanging from the case or box is to be lifted up and cover the two objects from the 5–month old
infants vision. Within the third step the empty hand of the researcher doing the experiment would come in from the same hole that it first came
through when it first placed the two objects in the case. The forth step of the experiment would consist of the hand taking one of the two objects from

Title: Impact of Capital Structure and Dividend Policy on Shareholders' Value 1. Introduction
Dividend policy has been an issue of interest in financial literature as many theories have been established to estimate weather this effects the overall
value of the firm.Dividend policy connotes to the payout policy, which managers pursue in deciding the size and pattern of cash distribution to
shareholders over time. Managements' primary goal is shareholders' wealth maximization, which translates into maximizing the value of the company
as measured by the price of the company's common stock. This goal can be achieved by giving the shareholders a "fair" payment on their investments.

26. Research On Magnetic Therapy
Psychological Claim
In the alternative medicine space, there is an assertion that magnetic therapy works to relieve pain. The retail industry has exploited this belief and has
turned the industry into a $1billion dollar industry (Palermo, 2015.)

The null hypothesis is there is no change in the level of pain between a person wearing the bracelets and a person not wearing the bracelets.
To test the hypothesis a sample of Fibromyalgia patients, through a partnership with chronic pain specialists, should be selected. An ideal sample
should include at least 60 participants evenly divided into two groups, a control group and an experiment group. In order to prevent the specialist from
treating the two groups differently, the specialist should not know which group the participants are in. Each participant should be fitted with identical
looking ankle and wrist bracelets, the control group will have non–magnetic bracelets and the experiment group will be magnetic. The specialist will
then see each patient each week for one month and document the results of their pain, as typically chronicled by the specialist.
After the experiment is complete, the results will be compiled by group and by participant variables such as age, gender, number of years the
participant has been diagnosed with Fibromyalgia, and other treatments tried. These results will be analyzed for correlations.
In a perfect study, the results for the full cohort will show the hypothesis is true or untrue, with no ambiguity. However, the results are typically not that

27. Animal 's Ability Foraging Theory
Introduction
Within certain environments such as casinos or betting houses, it is not uncommon to see individuals choose sub–optimally, meaning individuals will
often choose options that offer a high reinforcement outcome but with a lower probability of it occurring than a safer choice that would offer less
reinforcement but more reliably. In animals, it would be expected not to see this behaviour, for instance,optimal foraging theory (Pyke, 1984) argues
that an animal 's ability forage ultimately effects there overall evolutionary fitness in terms of ability to survive and the ability for the genes to be
passed on. Therefore, choosing risky behaviour would ultimately be a deficit to their survival. However rather Paradoxically, animals do indulge in
very similar gambling behaviours to that seen in humans (Stagner & Zentall, 2010).
Gipson, Alessandri, Miller, and Zentall (2009)was able to show this phenomenon to which they provided pigeons with two alternative keys a 50%
discriminative chain, meaning it had two light that represented reinforcement or no reinforcement. A secondly akey that provided food 75%
reinforcement on a non–discriminatory chain, meaning that it had a single contingency. what they found was that pigeons would choose the 50%
alternative as opposed to the 75% chain despite it providing far more food Stagner and Zentall (2010) at a better rate. Implying that gambling

28. S. Albus Experiment
The aim of this experiment was to observe the effect different concentrations of Dettol had on the growth of S. albus. The highest concentration of
Dettol (100% – D) was predicted to be the most effective solution to kill and stop the growth of this particular bacteria. This can be justified as S.
albus is gram–positive; easier bacteria to kill, developing resistance slower than a gram–negative. Therefore, the highest concentration of antibiotic
should be – and was – the most successful in changing the pH levels, and killing S. albus. Through discussion and analysis of the results collected
through the experiment, it can be concluded that there is higher chance of killing and the growth of this particular bacteria if 100% Dettol is used.
When ... Show more content on Helpwriting.net ...
It can be inferred that the more Dettol used, the larger the zone of inhibition will be. This was predicted as Dettol is an antibacterial solution,
therefore the higher the concentration is, the more effective the substance is in killing bacteria; S. albus. Though the 100% Dettol concentration (D)
is clearly the most effective in stopping the growth of S. albus (average zone of inhibition diameter being 20.12 mm), it may not be a healthy choice
if using the product on skin. After looking closely at the Agar plate, 'D' had burned away at parts of the disc, evidencing that using 100% Dettol on
your skin may lead to burns, justifying why it is not recommended on the company's bottle or official website.
Through the analysis and understanding of the results table and concepts, it is evident that the smallest diameter is solution 'A' (6mm) which can be
compared to the largest diameter – that being solution 'D' (23mm). This idea assists in justifying the hypothesis and research question as S. albus was
able to successfully grow in the incubator (hence why humans or warm–blooded animals are generally the host of this bacteria), and the highest

Methods of Research
Research, systematic inquiry aimed at the discovery of new knowledge, is a central ingredient of the scientific method in psychology. It provides the
key to understanding the degree to which hypotheses (and the theories behind them) are accurate. Just as we can apply different theories and
hypotheses to explain the same phenomena, we can use a number of alternative methods to conduct research.

* What is an advantage of the survey method?
The survey method can be advantageous to show that a political candidate would be popular amongst Latino votes because a larger population can be
surveyed. This would show the attitudes of those surveyed. * What is a disadvantage of the survey method?
The disadvantage is that the participants may not accurately or honestly answer the questions for fear of having socially unacceptable attitudes.

31. Adhesive Patch Test
Melanoma diagnoses are solely dependent on visual assessment of pigmented lesions, which leaves a margin of error when deciding lesions to
biopsy; in turn, this leads to many invasive biopsies yielding negative results (Ferris et al., 2017). This wastes valuable resources: money,
dermatologists' time, pathologists' fees (Gerami et al., 2017). The purpose of my research was to test the effects of a non–invasive adhesive patch test
in improving melanoma diagnoses. My research question was: How does the use of DermTech non–invasive adhesive patch test impact overall
melanoma diagnosis in a dermatology clinic? My alternative hypothesis was that the DermTech noninvasive adhesive patch test would improve
diagnosis. My null hypothesis was ... Show more content on Helpwriting.net ...
Therefore, measuring quantitative statistics of negative invasive biopsies was an appropriate method. I also assumed that there are no other changing
factors in the clinic that impact melanoma diagnosis. This lowered the external validity of my research and made it harder to generalize it to other
clinics, in other parts of the world. Although, the DermTech adhesive patch test claims to work for all abnormal/atypical skin lesions (Gerami et al.,
2017), I only studied melanoma due to the limited number of patients at my clinic.
For my research sub–question, I compared the results of patients that had lesions biopsied and had the DermTech test performed on the same lesion. I
assumed that the invasive biopsy always yielded correct results because the noninvasive DermTech was compared against it. I also had to assume that
the any results coming from the DermTech lab that claim to be indecisive were negative since they have no utility in the diagnosing procedure.
My external validity was low since I only had access to one pathology lab and one dermatology clinic. Furthermore, the clinic only had one
dermatologist whose diagnoses I measured. The dermatologist did not account for all age groups, levels of experience etc.
My research had high internal validity since the same dermatologist and nurses remained constant throughout the course of the data that I collected.

The Chicory was pollinated by a total of 18 pollinators (8 Wasps, 2 Bumble Bees, 8 Honeybees). The Knapweed was pollinated by a total of 8

As discussed before, in order to study the structural attractiveness of a plant it needed to be considered "significant" or have at least 30 points of
pollinator data. The above bar graph displays the only two observed plants that had 30 points of pollinator data over the course of the three days. The
Goldenrod plant had 35 points of data and the Aster plant had 42 points of data, making them both significant enough to study further. Previous work
by Koch classified both these plants as Composite Flowers (1930). Given their similar internal structures, we would focus on a difference in flower
length, an external structure, to explain the differences in pollinator visitations. Previous work by Gross& Werner has shown the average flower length
of Goldenrod plants to be Вѕ of an inch (1983). Previous work by Harder has shown the average flower length of Aster plants to be 2 inches (1985).

Hypothesis Testing
Hypothesis testing is basically a process that uses statistical inference to test claims about population parameters. In hypothesis testing we begin by
making a tentative assumption about a population parameter. This assumption is called the null hypothesis and is denoted by Ho. We then define
another hypothesis, called the alternative hypothesis, which is the opposite of what is stated is the null hypothesis. The alternative hypothesis is denoted
by Ha. The hypothesis testing procedure involves using data from a sample to test the competing claims indicated by the null and alternate hypotheses.
Testing the hypothesis is similar to a criminal trail. Ho: The defendant is innocent Ha: The... Show more content on Helpwriting.net ...
Testing this will entail taking a sample of the 2–liter bottles and measuring their contents. In terms of the hypotheses formulation you give the
company the benefit of the doubt and assume that their claim is true. Using this approach the hypothesis will be stated as given below: H0: [pic]> 67
Ha: [pic]< 67
In a situation where we are testing the validity of an assumption, the null hypothesis is generally formulated based on the assumption. The alternate
hypothesis is formulated so that the rejection of the null will provide statistical evidence that the stated assumption is incorrect.
Decision Making
A hypothesis–testing situation involving decision making occurs when a decision maker must choose between two courses of action, one associated
with the null hypothesis and the other with the alternate hypothesis. For example, on the basis of a sample of parts from a shipment that has just been
received, a quality control inspector must decide whether to accept the shipment or return it to the supplier because it does not meet specifications.
Assume that a specification for the part indicates a mean length of 1 inch per part is required. If the average length of the part is greater than or less
than the 1inch standard, the parts will cause quality problems. In this case the null and alternative hypotheses would be formulated as follows: H0:

Bower studied the effect of creating a visual image to assist verbal recall. In one experiment, the participants were given out 100 different cards,
one at a time which each had two unrelated words on it , like 'cat' and 'tree'. The participants either had to remember the pair or create a visual
scene in which both objects were featured. When the participants were given a cued recall test (given the first of each pair of words), the group
who created a visual scene recalled 80% of the target words, whereas those who did not remember an image could only recall 45%. It was proven
that the images which were more unusual were easier to remember, for example it would be better to visualise a cat living inside a tree, rather than a
cat climbing up a tree as the first scene is more unlikely and bizarre.
Experimental Hypothesis:
Individuals are more likely to recall words if it is given in picture form rather than just the word shown alone.
Null Hypothesis:
Being shown images compared to just being showing the word does not change an individual's ability to recall the word.

will happen in the economy where there is monetary policy or fiscal policy intervention are appropriate in assisting policy–makers understand the
possible implications of decisions they make or are under consideration. However, they are rarely complete models and often outcomes cannot be
predicted. Reintroduction of a theory suggests that new evidence in support of the theory has been reported. 3. Should a theory be discarded if it
does not specify the means of achieving a stated objective? Explain your answer. The theory itself doesn't have to specify the means of achieving a
