BUSI 620 Questions for Critical Thinking 3 Salvatore’s Chapter 6: a. Discussion Questions: 1, 7, and 15. b. Problems: 7 and appendix problems 1 and 3 (pp. 256–257). Note: 1. Revised P7: Just construct the diffusion index from month 2 to 3. In this problem, we have three leading indicators. The diffusion index from month 1 to 2 is 66.7 (=2/3) because two indicators move up and move down (see p. 236). 2. Appendix problem 1: Delete “Eliminating the data for 2000.” You need to calculate the moving average forecasts and RMSEs for year 2000, not the whole data period. 3. Appendix problem 3: Compare RMSEs for moving average and exponential forecasts to answer “Is this a better forecast than the moving average” (see also p. 234)? Use 166.63, the mean of all 36 months, as the initial forecast for Jan. 1998 for both exponential smoothing forecasts. Salvatore’s Chapter 7: a. Discussion Questions: 3, 11, and 12. b. Problems: 4, 12, and 13. Note: 1. P4: Ms. Smith should hire workers as long as their marginal revenue product (MRP) exceeds their marginal resource cost (MRC) and until MRP=MRC. MRP=MR x MP = P x MP = $10 x MP (use information in the problem to calculate MP). MRC=wages=$40. 2. P12(a): Calculate Q when L=1and K=1, and L=2 and K=2. Then compare and answer the question about the returns to scale. 3. P12(b): Given K=1, show the change in Q if L changes from 1 to 2 and 2 to 3. Answer the question about diminishing returns. 4.

InstructionDue Date: 6 pm on October 28 (Wed) Part IProbability and Sampling Distributions1.Thinking about probability statements. Probability is measure of how likely an event is to occur. Match one of probabilities that follow with each statement of likelihood given (The probability is usually a more exact measure of likelihood than is the verbal statement.)Answer0 0.01 0.3 0.6 0.99 1(a) This event is impossible. It can never occur.(b) This event is certain. It will occur on every trial.(c) This event is very unlikely, but it will occur once in a while in a long sequence of trials.(d) This event will occur more often that not.2. Spill or Spell? Spell-checking software catches "nonword errors" that result in a string of letters that is not a word, as when "the" is typed as "the." When undergraduates are asked to write a 250-word essay (without spell-checking), the number X of nonword errors has the following distribution:Value of X01234Probability0.10.20.30.30.1(a) Check that this distribution satisfies the two requirements for a legitimate assignment of probabilities to individual outcomes.(b) Write the event "at least one nonword error" in term of X (for example, P(X >3)). What is the probability of this event?(c) Describe the event X ≤ 2 in words. What is its probability? 3. Discrete or continuous? For each exercise listed below, decide whether the random variable described is discrete or continuous and explains the sample space.(a) Choose a student in your class at random. Ask how much time that student spent studying during the past 24 hours.(b) In a test of a new package design, you drop a carton of a dozen eggs from a height of 1 foot and count the number of broken eggs.(c) A nutrition researcher feeds a new diet to a young male white rat. The response variable is the weight (in grams) that the rat gains in 8 weeks.4. Tossing Coins(a) The distribution of the count X of heads in a single coin toss will be as follows. Find the mean number of heads and the variance for a single coin toss.Number of Heads (Xi)01mean:Probability (Pi)0.50.5variance:(b) The distribution of the count X of heads in four tosses of a balanced coin was as follows but some missing probabilities. Fill in the blanks and then find the mean number of heads and the variance for the distribution with assumption that the tosses are independent of each other.Number of Heads (Xi)01234mean:Probability (Pi)0.06250.0625variance:(c) Show that the two results of the means (i.e. single toss and four tosses) are related by the addition rule for means. (d) Show that the two results of the variances (i.e. single toss and four tosses) are related by the addition rule for variances (note: It was assumed that the tosses are independent of each other). 5. Generating a sampling distribution. Let's illustrate the idea of a sampling distribution in the case of a very small sample from a very small .

Instructions and Advice: · This assignment consists of six questions. They each have lots of parts but most of them are very short! · Data for Questions 3 and 6 are in the companion Excel spreadsheet <Asst3_2013_Data.xlsx>. · Present the parts of your answers in the same order as the questions are asked. · Do not include any original data in your printed submission. · Maintain all precision in your calculator or in Excel as you do your multi-step computations. Round off to fewer decimal places only when you write your work and the final answer down to hand in. · When formatting numbers in Excel, display only as many decimal places as provide decision-making value to the reader. Question 1 – Interpreting or Misinterpreting Correlation a) Various factors are associated with the gross domestic product (GDP) of nations. State whether each of the following statements is reasonable or not. If not, explain the blunder. (i) A correlation of –0.722 shows that there is almost no association between GDP and Infant Mortality Rate. (ii) There is a correlation of 0.44 between GDP and Continent. (iii) There is a very strong correlation of 1.22 between Life Expectancy and GDP. (iv) The correlation between Literacy Rate and GDP was 0.83. This shows that countries wanting to increase their standard of living should invest heavily in education. b) An article in a business magazine reported that Internet E-commerce has doubled nearly every three years. It then stated that there was a high correlation between sales made on the Internet and year. Do you think this is an appropriate summary? Explain in one sentence. c) Simpson’s Paradox can occur in regression, when a relationship between variables within groups of observations is reversed if all the data are combined. Here is an example. Group X Y Group X Y 1 1 10.1 2 6 18.3 1 2 8.9 2 7 17.1 1 3 8.9 2 8 16.2 1 4 6.9 2 9 15.1 1 5 6.1 2 10 14.3 (i) Make a scatterplot of the data for Group 1 and add the least squares line. Describe the relationship between Y and X for Group 1. Find the correlation (using Excel). (ii) Do the same for Group 2. (iii) Make a scatterplot using all 10 observations and add the least squares line. Find the correlation (using Excel). (iv) Summarize your findings in one or two sentences. d) Since 1980, average mortgage interest rates in the U.S. have fluctuated from a low of under 6% to a high of over 14%. Is there a relationship between the amount of money people borrow and the interest rate that’s offered? Here is a scatterplot of Total Mortgages in the U.S. (in millions of 2005 dollars) vs. Interest Rates at various times over the past 26 years. The correlation is -0.84. (i) Describe the relationship between Total Mortgages and Interest Rate. (ii) If we standardized both variables, what would the correlation coefficient between the standardized variables be? (iii) If we were to measure Total Mortgages in thousands of dollars instead of millions of dollars, how would the.

You now have to start construction on your restaurants. The financing is coming from the United Arab Emirates, the materials are coming from Mexico and China, the engineering and technology are coming from Israel , and the labor will be hired locally within these countries by your management team from the United States. You invite all of the players to the headquarters in the United States for a big meeting to explain the project and get to know one another. The people seem to be staying with their own groups and not mingling. What is the cultural phenomenon at play here (what is it called/ term)? How do you explain the lack of intercultural communication and interaction? What do you know about these cultures—specifically their economic, political, educational, and social systems—that could help you in getting them together? What are some of the contrasting cultural values of these countries? You are concerned about some of the language barriers as you start the meeting, particularly the fact that the United States is a low-context country, and some of the countries present are high-context countries. Furthermore, you only speak English, and you do not have an interpreter present. How will this affect the presentation? What are some of the issues you should be concerned about regarding verbal and nonverbal language for this group?

Part 1: SQL/Database work Scenario Development of a relational database system for a food producing company FoodRU is a Leicester-based food producing company. The company wants to keep details regarding both past and present employees and their assignment to shifts over time. At present, there are three defined shift patterns; the morning shift starts at 6am and finishes at 2pm, the day shift starts at 9am and finishes at 5pm, and the evening shift starts at 4pm and finishes at 12am (midnight). However, management have already indicated that they may need to add further shift patterns in the future (e.g., by adding a night shift to the existing ones so that the company can meet a high user demand for their foods). They therefore require shift details to be stored within a separate Shift table, with attributes that allow the storage of a shift name with its associated start and finish times (use the 24 hour clock for these times). Past and present employee details are to be kept in the same Employee table, and the details to be kept are the employee’s unique 6 digit reference number, the first name, surname and any other names (if there are any) of the employee, the employee’s gender, contact address and contact telephone, the date on which the employee started his/her employment at the company and the date on which the employee finished his/her employment at the company (should s/he be a past employee). Details regarding staff assignments to shifts include the date that an employee was allocated to work a particular shift, and the date that s/he was taken off the shift (if not still assigned to it). Employees can be assigned to different shifts over time and even to the same shift over different time periods, although they cannot be assigned to more than one shift at any one time. A new employee may not yet be assigned to a shift. Tasks: 1. Provide the table specifications for the THREE tables that are required by FoodRU to store employee, shift and assignment details. That is, for each of the three tables, you should provide, in a suitable presentation format, the name of the table and a specification of each its attributes to include: • Attribute name • Attribute brief description as to its meaning • a description of the attribute’s data type/integrity (e.g., date field, character field of length 20, number field <= 10, etc. – you can use the Oracle data types within these descriptions if you want to) • An indication as to whether the attribute is a primary key attribute and/or foreign key attribute • An indication as to whether the attribute can or cannot take null values Make sure your design specifies the appropriate links between the three tables. Remember to write down any additional integrity you need to enforce either at a specific table level or across two or more tables, if this is required. Also, remember to write down any justifications for the data types/integrity or for any other design features that.

part 1: I attended an international conference on Biotechnology and one of the sessions I went to was on the subject of bio-engineering a "death gene" that could be introduced into the mosquito population and destroy every mosquito on earth. The discussion that ensued was about the ethics of such a thing. I want you to tell how you feel about introducing such a gene. Look up something about this. Your reference does not have to be about this particular gene, but can be about anything that relates to the discussion. Remember to cite your reference, and write at least 150 words part 2: Respond to another student respond to this I think that with regulation of the mosquito communities would be a good thing. Mosquitos carry many dangerous diseases and if we can lower the population we can slow the rate of transmission of these diseases. This could save many many lives around the world. I would be hesitant though to release the genetically engineered mosquitos into the environment. In the article I read they releases sterile male mosquitos into the environment. This I feel is a safer way to regulate because we are not altering any genes we are just regulating a naturally occurring issue in nature. Sterile males cannot pass on the genes and also male mosquitos are not the ones who would be likely to pass on the diseases. The article stated that only females bite and therefore males would not be capable of spreading the diseases. With sterile males being released there will be less mosquitos due to lack of repopulation. This will still allow organisms relying on mosquitos for food to still be able to survive with less risk to humans. They are an invasive species so it would help to eliminate the spread of mosquitos to different areas. This will keep the spread of disease throughout areas. I do not think it is right to alter the genes for human use though. It is not how nature had intended. If the gene pops up naturally in the population then it should not be taken out but we should not introduce it due to humans "playing God" with genetics.
