So it\'s sample or population ? So it\'s sample or population ? Solution In the Experement setup, Under the intrested study regarding we dinfe the population units and sample units. here i give the general defination of the population and sample unit as follow; population : A population is any entire collection of people, animals, plants or things from which we may collect data. It is the entire group we are interested in, which we wish to describe or draw conclusions about. Sample: A unit is a person, animal, plant or thing which is actually studied by a researcher; the basic objects upon which the study or experiment is carried out. For example, a person; a monkey; a sample of soil; a pot of seedlings; a postcode area; a doctor\'s practice. in generally samples are drawn from the popultaion units, that samples units reprsents tha whole population. In the infrance we are working on the sample and conclude on the basis of the sample information we draw the population information..

Selecting a sample 
This document discusses key concepts in quantitative research methods including research, samples, populations, random and non-random sampling techniques. It defines research as a careful investigation to discover new facts or interpret existing facts. A sample is a subset of a population used to gain insights about the whole. Random sampling methods like simple random sampling, stratified sampling, and cluster sampling aim to select representative samples, while non-random methods like convenience and purposive sampling are not generalizable. The document also discusses qualitative research and purposive sampling techniques.
BUSINESS RESEARC - POPULATION, SAMPLE,SAMPLING_final.docx
The document defines key concepts in research methodology including population, sample, and sampling. A population refers to the total group of interest, while a sample is a subset selected to represent the population. There are different types of populations such as the target and respondent populations. Sampling is the process of selecting a sample and can be done through probability or non-probability methods. Probability sampling allows for stronger statistical inferences about the whole population, while non-probability sampling is easier but only generalizable to the sample. Respondents answer questions in a study, while subjects voluntarily participate in a study.

A population is the entire group being studied, while a sample is a subset of the population that is selected for analysis. A hypothesis is a proposed explanation for a phenomenon that can be tested through research. There are two main types of hypotheses: the null hypothesis proposes there is no relationship between variables, while the alternative hypothesis proposes there is a relationship. Hypotheses can also be directional, predicting the nature of a relationship, or nondirectional, simply predicting a difference but not the direction.

Types of probability sampling22.docx
This document defines key concepts in probability and non-probability sampling. It explains that probability sampling uses random selection to select samples from a population, with four main types listed: simple random sampling, stratified sampling, systematic sampling, and cluster sampling. Non-probability sampling relies on the researcher's judgment rather than random selection, with common types being convenience sampling, consecutive sampling, quota sampling, judgmental sampling, and snowball sampling. Examples are provided to illustrate each sampling technique.
SAMPLING Theory.ppt
1) Sampling involves collecting data from a subset of individuals (the sample) rather than from the entire population.
2) There are two main types of sampling: probability sampling, where each individual has a known chance of being selected, and non-probability sampling, where the probability of selection is unknown.
3) Common probability sampling methods include simple random sampling, stratified sampling, systematic sampling, and cluster sampling. Non-probability methods include quota sampling and snowball sampling.

The Scientific Method
Steps in the Scientific Method
There is a great deal of variation in the specific techniques scientists use explore the natural world. However, the following steps characterize the majority of scientific investigations:
Step 1: Make observations
Step 2: Propose a hypothesis to explain observations
Step 3: Test the hypothesis with further observations or experiments
Step 4: Analyze data
Step 5: State conclusions about hypothesis based on data analysis
Each of these steps is explained briefly below, and in more detail later in this section.
Step 1: Make observations
A scientific inquiry typically starts with observations. Often, simple observations will trigger a question in the researcher's mind.
Example: A biologist frequently sees monarch caterpillars feeding on milkweed plants, but rarely sees them feeding on other types of plants. She wonders if it is because the caterpillars prefer milkweed over other food choices.
Step 2: Propose a hypothesis
The researcher develops a hypothesis (singular) or hypotheses (plural) to explain these observations. A hypothesis is a tentative explanation of a phenomenon or observation(s) that can be supported or falsified by further observations or experimentation.
Example: The researcher hypothesizes that monarch caterpillars prefer to feed on milkweed compared to other common plants. (Notice how the hypothesis is a statement, not a question as in step 1.)
Step 3: Test the hypothesis
The researcher makes further observations and/or may design an experimentto test the hypothesis. An experiment is a controlled situation created by a researcher to test the validity of a hypothesis. Whether further observations or an experiment is used to test the hypothesis will depend on the nature of the question and the practicality of manipulating the factors involved.
Example: The researcher sets up an experiment in the lab in which a number of monarch caterpillars are given a choice between milkweed and a number of other common plants to feed on.
Step 4: Analyze data
The researchersummarizes and analyzes the information, or data, generated by these further observations or experiments.
Example: In her experiment, milkweed was chosen by caterpillars 9 times out of 10 over all other plant selections.
Step 5: State conclusions
The researcher interprets the results of experiments or observations and forms conclusions about the meaning of these results. These conclusions are generally expressed as probability statements about their hypothesis.
Example: She concludes that when given a choice, 90 percent of monarch caterpillars prefer to feed on milkweed over other common plants.
Often, the results of one scientific study will raise questions that may be addressed in subsequent research. For example, the above study might lead the researcher to wonder why monarchs seem to prefer to feed on milkweed, and she may plan additional experiments to explore this question. For example, perhaps the milkweed has higher ...
Sampling Techniques.docx
Sampling is selecting a subset of a larger population to gather information about and make inferences regarding the entire population. There are two main types of sampling: probability sampling, where every member of the population has a known chance of being selected, and non-probability sampling, where samples are selected in a non-random manner. Some common probability sampling techniques include simple random sampling, systematic sampling, stratified sampling, and cluster sampling. Common non-probability sampling techniques include convenience sampling, judgmental sampling, and quota sampling. The key aspects of sampling are defining the target population, determining a sampling frame, choosing a sampling technique, and determining sample size.
Epidemiology Depuk sir_ 1,2,3 chapter,OK
Epidemiology is defined as the study of the distribution and determinants of health-related states or events in populations, and the application of this study to control health problems. The aims of epidemiology include describing disease occurrence, assessing disease importance, explaining disease etiology, predicting disease, evaluating prevention and control, and controlling disease distribution. Common epidemiological study designs include cohort studies, case-control studies, cross-sectional studies, and occupational studies. Key epidemiological concepts include incidence, prevalence, sensitivity, specificity, and confounding factors.
Introduction To Statistics
This document defines key statistical concepts:
- Statistics is the subject that deals with collecting, analyzing, and interpreting data. It can also refer to the data itself or summary measures calculated from samples.
- A population includes all individuals or objects with common characteristics being studied. A sample is a subset of a population selected to represent it.
- A parameter is a characteristic of the entire population, such as the population mean, which remains fixed. A statistic is a characteristic calculated from a sample, such as the sample mean, which can vary between samples.

Help me with these questions please.1. Name four characteristics t.pdf
Help me with these questions please.
1. Name four characteristics that are used to describe single variable data.
2. What are the advantages of using a stemplot over a histogram? What are the disadvantages?
3. What are the advantages of using the mean as the center? What are the disadvantages?
4. What are the advantages of using the median as the center? What are the disadvantages?
5. What type of graph is used for bivariate data?
6. What is the difference between explanatory and response variables?
7. What does the correlation coefficient, r, measure?
8. What is the range of values of r?
9. What does the coefficient of determination, r^2, measure?
10. What is the range of values of r^2?
11. How is a residual plot constructed?
12. How is a residual plot interpreted?
Solution
1) i. Randomness ii. Presentable iii. Reliable iv. Genuine
2) Stemplot gives list of values as it is in a easy form of presentation.
Disadvantage is while histogram enables comparison about the data, stemplot just presents data
in a grouped form
3) Mean is easily understood and also a good central measure. So many distributions we find that
sample mean estimates population parameter but disadvantage of mean is it is affected by
extreme items or outliers thus giving wrong picture about average.
4) Median is reliable and not affected by outliers as it is affectd only by the order of the item.
The disadvantage is that for continuous data, it is not possible always to arrange in ascending and
find median.
5) Planar graph with 2 coordinates used for bivariate data.
6) Explanatory variable is the independent variable which can take any value but response
variable value depends on the value of explanatory variable
7) Correlation coefficient measures the dependence or association of two variables
8) r lies between -1 and +1
9) Coefficient of determination represent variation of y wrt x. It is square of r, and always
positive thus gives a clear picture of relation between x and y.
10) r^2 varies from 0 to 1
11) Residual plot is constructed using scatter diagram and least square line.
REsidue plot is the deviation of actual from estimated regression curve.
12) REsidual plot is the absolute difference of y and y estimate..

Epidemiology is defined as the study of the distribution and determinants of health-related states or events in populations, and the application of this study to control health problems. The aims of epidemiology include describing disease occurrence, assessing disease importance, explaining disease etiology, predicting disease, evaluating prevention and control, and controlling disease distribution. Common epidemiological study designs include cohort studies, case-control studies, cross-sectional studies, and occupational studies. Key epidemiological concepts include incidence, prevalence, sensitivity, specificity, and confounding factors.
Introduction To Statistics
This document defines key statistical concepts:
- Statistics is the subject that deals with collecting, analyzing, and interpreting data. It can also refer to the data itself or summary measures calculated from samples.
- A population includes all individuals or objects with common characteristics being studied. A sample is a subset of a population selected to represent it.
- A parameter is a characteristic of the entire population, such as the population mean, which remains fixed. A statistic is a characteristic calculated from a sample, such as the sample mean, which can vary between samples.

Give examples of system which can achieve some security requirement?
Solution
Answer:
The security of the system depends upon these four pillars :
1. Secrecy
2. Integrity
3. Accountability
4. Availibility
Every computer must be aware about the security and must decide what is security to it. It is like
a legal law in some country can be illegal for other country..
Help me with these questions please.1. Name four characteristics t.pdf
Help me with these questions please.
1. Name four characteristics that are used to describe single variable data.
2. What are the advantages of using a stemplot over a histogram? What are the disadvantages?
3. What are the advantages of using the mean as the center? What are the disadvantages?
4. What are the advantages of using the median as the center? What are the disadvantages?
5. What type of graph is used for bivariate data?
6. What is the difference between explanatory and response variables?
7. What does the correlation coefficient, r, measure?
8. What is the range of values of r?
9. What does the coefficient of determination, r^2, measure?
10. What is the range of values of r^2?
11. How is a residual plot constructed?
12. How is a residual plot interpreted?
Solution
1) i. Randomness ii. Presentable iii. Reliable iv. Genuine
2) Stemplot gives list of values as it is in a easy form of presentation.
Disadvantage is while histogram enables comparison about the data, stemplot just presents data
in a grouped form
3) Mean is easily understood and also a good central measure. So many distributions we find that
sample mean estimates population parameter but disadvantage of mean is it is affected by
extreme items or outliers thus giving wrong picture about average.
4) Median is reliable and not affected by outliers as it is affectd only by the order of the item.
The disadvantage is that for continuous data, it is not possible always to arrange in ascending and
find median.
5) Planar graph with 2 coordinates used for bivariate data.
6) Explanatory variable is the independent variable which can take any value but response
variable value depends on the value of explanatory variable
7) Correlation coefficient measures the dependence or association of two variables
8) r lies between -1 and +1
9) Coefficient of determination represent variation of y wrt x. It is square of r, and always
positive thus gives a clear picture of relation between x and y.
10) r^2 varies from 0 to 1
11) Residual plot is constructed using scatter diagram and least square line.
REsidue plot is the deviation of actual from estimated regression curve.
12) REsidual plot is the absolute difference of y and y estimate..

Dont change the templates, and just fill out the TODO parts on .pdf
Don\'t change the templates, and just fill out the // TODO parts on below of templates, please.
Instruction
Reimplement a program using List and ArrayList . Recall that it is a
little tricky to merge arrays of window orders when the arrays may have dierent
sizes. Using List to represent arrays of window orders is more convenient since
we can add a new window order if its size is not found in the existing orders.
To this end, we have added a new class called TotalOrder , which represents
a list of window orders. It contains methods to add a single window order or
another total order. These methods will ensure that the orders are propertly
merged by window sizes.
What to implement?
You will use in the methods for classes described above. The provided code
template has instruction in the comments above the methods that you will
implement.
Output
20 apartments with (Living room: 5 (6 X 8 window))(Master bedroom: 3 (4 X 6 window))
15 apartments with (Living room: 5 (6 X 8 window))(Master bedroom: 3 (4 X 6 window))
(Guest room: 2 (5 X 6 window))
10 apartments with (Living room: 5 (6 X 8 window))(Master bedroom: 3 (4 X 6 window))
(Guest room: 2 (5 X 6 window))(Guest room: 2 (5 X 6 window))
Window orders are:
225 6 X 8 window
135 4 X 6 window
70 5 X 6 window
Note
TotalOrder:
o add(WindowOrder newOrder): To add the “newOrder” at first check if a similar order is
already stored in the array list. You should check this within a loop structure. If it already exists
you should merge it with the similar window order using a method call to “add” (which is a
method declared in WindowOrder to merge the orders). Otherwise, simply add the “newOrder”
to the end of the array list through calling the “add” method of the array list. The method returns
the current object.
o add(TotalOrder that): this method makes use of the previous one. You should iterate over all of
the window orders listed in “that” and add them to the array list by passing each one of its
elements them as the input argument to the above “add” method.
o times(int num): for every element stored in the arraylist of the class, call “times” method and
pass “num” as the input argument to it.
o toString(): for every element stored in the arraylist, call its toString() method +”\ ”. Store the
result in a String variable and then return it.
- Apartment:
o orderForOneUnit(): create a new “TotalOrder” object. Add the window orders of every room
to the total order. Return the total order.
o totalOrder(): call the previous method to get the total order for one unit. Call the “times”
method of the total order and use number of apartments as input.
- Building:
o order(): declare and create a TotalOrder object. Add the total order of each apartment into the
object you just created and return it after the loop.

Directions Problem 1. A female with Muppetrus bristle mates with a .pdf
Directions: Problem 1. A female with Muppetrus bristle mates with a male with Flonasean body
color, producing the following counts: F1 Generation Males Disease-Disease WIT-Disease WT-
WT Disease-WT 243 239 Females WT-Disease Disease Disease WT-WT Disease-WT 254 254
Solution
Parents are heterozygous. Given that each parent has one disease phenotype at one locus and
wild type at other locus.
Female\'s disease phenotype is Muppetrus bristle. Let its symbol be WT.
Cross is: +/disease (phenotype Muppetrus) crossed to +/disease (phenotype Flonasean)
The answer cannot be homozygous lethal because WT-WT and Disease-Disease are there.
Similarly it cannot be autosomal recessive, because in females Disease-Disease is 0.
This means that the mode of inheritance is sex-linked recessive.
In Drosophila males, crossing over does not occur. Only one X chromosome, which comes from
the female parent. So, genotype of males will be \"WT (wild type)\" phenotype on X-
chromosome. In females Disease-Disease is zero because of this..

What suggestions would you offer to parents and teachers who want to.pdf
What suggestions would you offer to parents and teachers who want to socialize children into
more androgynous and flexible gender roles? Be specific.
Solution
A) Parents treat sons and daughters alike (interact
equally, are equally warm) except for behaviour related to gender roles
• Dolls, dress-up, helping an adult are encouraged with girls
• Rough and tumble play is encouraged with boys
• Parents react more positively when children play with toys typical for their sex
• Fathers are more likely to encourage behaviour associated with gender stereotypes.
B) Many teachers and schools make gender salient in the classroom - eg. Separate lines for boys
and girls
• Might call on boys more than girls
• Are more likely to scold boys more for disruptive behaviour
• Since most elementary school teachers are female, classroom activities, readings, wall
dressings, etc. might be more appealing for girls
• When boys are not interested in something they tend not to do it..

What features on the plasmid allows it to replicate independent o.pdf
What features on the plasmid allows it to replicate independent of the chromosomes
What features on the plasmid allows it to replicate independent of the chromosomes
Solution
Plasmids are the extra chromosomal DNA found in bacteria. Plasmids possesses a replicon or an
origin of replication of specific nucleotide sequence. This replicon helps the plasmids to replicate
independently. The tra genes or the transfer genes present in the plasmids helps them to get
transferred to the next generation with the help of relaxosome (a combination of DNA and tra
protein) which breaks one of the two strands of plasmid DNA and helps to unwind and it gets
treansferred throgh pilus. Mob genes also helps them for mobilisation during transformation.
Some plasmids undergo binary fission..

Although O_2 does not participate directly in the reactions of the TC.pdf
Although O_2 does not participate directly in the reactions of the TCA cycle, the cycle operates
only under aerobic conditions. Briefly explain this fact. How many ATP molecules are
generated during the complete oxidative degradation of phosphoenolpyruvate (PEP) to CO_2
and H_2O? Assume the glycerol phosphate shuttle is operating and show how you arrived at
your answer.
Solution
2) even though oxygen does not participate in the TCA Cycle but the ATP and NADPH
produced are passed in the ETC cycle where the oxygen acts as a electron transport.. Hence there
the role of oxygen takes place which is not found in the case of anaerobic situations..
3) when PEP gets converted to pyurvate I release 2 molecules of ATP.. But in this case only 1
ATP is produced as the one molecule of di-hydrooxyacetone phosphate converted to glyecerol-3-
phosphate by glycerol cycle hence in the glycolysis step 1 molecule gets reduced hence 1 ATP
gets reduced..!!.

Solution In the Experement setup, Under the intrested study regarding we dinfe the population units and sample units. here i give the general defination of the population and sample unit as follow; population : A population is any entire collection of people, animals, plants or things from which we may collect data. It is the entire group we are interested in, which we wish to describe or draw conclusions about. Sample: A unit is a person, animal, plant or thing which is actually studied by a researcher; the basic objects upon which the study or experiment is carried out. For example, a person; a monkey; a sample of soil; a pot of seedlings; a postcode area; a doctor's practice. in generally samples are drawn from the popultaion units, that samples units reprsents tha whole population. In the infrance we are working on the sample and conclude on the basis of the sample information we draw the population information.
