Compare and contrast the three types of responsibility centers. What is the best way to evaluate a manager's performance in each type of center? What is the problem with using only financial measures of performance?

In February 2021, the Chicago Tribune reported:“The overdose epidemic that has ravaged Chicago has not spared the nearby suburbs, some of which have death rates comparable to anything seen in the city, according to a report released this week by the Cook County Department of Public Health. ZIP codes in the towns of Worth, Broadview, Maywood, and Forest Park, areas that “have substantially lower median household incomes and higher poverty rates,” have been especially hard-hit, the report said.”In the article, they claimed that lower incomes were associated with higher overdose death rates and that overdose death rates are increasing over time. The data you have been analyzing wasn’t focused on Chicago, obviously. But do your results support the general gist of the statistical argument being made in this Tribune excerpt? Please address:• Do overdose death rates appear to be associated with per capita income (use scatterplot)?• Do overdose death rates appear to be increasing over time…

The Dow Jones Industrial Average (DJIA) and the Standard & Poor's 500 (S&P 500) indexes are used as measures of overall movement in the stock market. The DJIA is based on the price movements of 30 large companies; the S&P 500 is an index composed of 500 stocks. Some say the S&P 500 is a better measure of stock market performance because it is broader based. Suppose the closing price for the DJIA and the S&P 500 for 144 days in a certain year are as provided in the file closingprices3.xlsx. (a) Develop a scatter chart for these data with DJIA as the independent variable. What does the scatter chart indicate about the relationship between DJIA and S&P 500? The scatter chart indicates there may be a positive linear relationship between DJIA and S&P 500. The scatter chart indicates there may be no noticeable linear relationship between DJIA and S&P 500. The scatter chart indicates there may be a negative linear relationship between DJIA and S&P 500. (b) Develop an estimated linear…

Here are the countries with the five highest estimated costs of software piracy: United States ($9.1 billion), China ($8.7 billion), India ($2.7 billion), France ($2.1 billion), United Kingdom ($1.9 billion). Among these five countries, the United States has 37.1% of the cost of piracy. Is it correct to conclude that the United States has 37.1% of the total cost of piracy for all countries? What do these results tell us about the costs of piracy in the other countries not included here?

If the report underestimated the increase in STEM jobs over the period 2020-2028 by 11%, and overestimated the decrease in manufacturing and production jobs by 26% over the same period, what would be the impact on the actual number of jobs available in total across these sectors?

1. The Refuel Agency determined that college students spent $39.6 billion on food in 2020. Identify the population and the variable in this study.

Joseph Randal has just been named the director of alumni relationships at a local university. Alumni donations are an important source of revenue for colleges and universities. If administrators could determine the factors that could lead to increases in the percentage of alumni who make a donation, they might be able to implement policies that could lead to increased revenues. Research shows that students who are more satisfied with their contact with teachers are more likely to graduate. As a result, one might suspect that smaller class sizes and lower student/faculty ration might lead to a higher percentage of satisfied graduates, which in turn might lead to increases in percentage of alumni who make a donation.    Joseph is feeling an extra pressure to increase total giving to the university because of recent budget cuts. Joseph is also feeling pressured to increase the percentage of alumni to give. Joseph found this new metric called average alumni giving rate U.S. News &…

How common are financial cost or contractual constraints associated with smartphone ownership? A survey of smartphone owners found that 48% of the 18- to 29-year-olds, 38% of the 30- to 49-year-olds, 25% of the 50- to 64-year-olds, and 19% of those age 65 or older have reached the maximum amount of data they are allowed to use as part of their plan, at least on occasion. Suppose the survey was based on 200 smartphone owners in each of the four age groups: 18 to 29, 30 to 49, 50 to 64, and 65+. a.  At the 0.05 level of significance, is there evidence of a differ-ence among the age groups in the proportion of smartphone owners who have reached the maximum amount of data they are allowed to use as part of their plan, at least on occasion? b. Determine the p-value in (a) and interpret its meaning. c.  If appropriate, use the Marascuilo procedure and a=0.05 to determine which age groups differ.

Classify each scenario as a meta-analysis or a case study.  a. An economist studies the various factors that could make it more likely for people to remain in their current jobs. b. A researcher collects data from previous studies on the price of auto insurance premiums in a particular state over the past 10 years. c. A food scientist examines the factors that influence the intensity of heat that is released from burning charcoal in an outdoor grill. d. A researcher analyzes 15 previous studies about the most effective long term weight loss strategies.

The Dow Jones Industrial Average (DJIA) and the Standard & Poors 500 (S&P500) indexes are used as measures of overall movement in the stock market. The DJIA is based on the price movements of 30 large companies; the S&P 500 is an index composed of 500 stocks. Some say the S&P is a better measure of stock market performance because it is broader based. The closing prices for the DJIA and S&P500 for 20 weeks starting on 9/9/2005 are included in cells E1 to G21. The DJIA data is in cells F1 to F21 and the data for S&P 500 is in cells G1 to G21. Both data sets have labels in first row.      Develop the estimated regression equation using DJIA as the independent variable. Place output in cell H1     Is the relationship between DJIA and S&P500 significant using alpha .05?     Did the estimated regression equation provide a good fit?

A mail-order catalog business that sells personal computer supplies, software, and hardware maintains a centralized warehouse for the distribution of products ordered. Management is currently examining the process of distribution from the warehouse and has the business objective of determining the factors that affect warehouse distribution costs. Currently, a handling fee is added to the order, regardless of the amount of the order. Data that indicate the warehouse distribution costs and the number of orders received have been collected over the past 24 months and can be seen below:     Months Distribution Cost ($thousands) Number of Orders 1 52.95 4015 2 71.66 3806 3 85.58 5309 4 63.69 4262 5 72.81 4296 6 68.44 4097 7 52.46 3213 8 70.77 4809 9 82.03 5237 10 74.39 4732 11 70.84 4413 12 54.08 2921 13 62.98 3977 14 72.30 4428 15 58.99 3964 16 79.38 4582…

The human race is in danger warns authors Shanna Swan and Stacey Colina in their book COUNT DOWN: How Our Modern World Is Altering Male and Female Reproductive Development, Threatening Sperm Counts, and Imperiling the Future of the Human Race.   A study Swan cites in “Count Down” found that just over a quarter of men experiencing erectile dysfunction were under 40. That may be, in part, because testosterone levels have been dropping at 1 percent per year since 1982.   The outlook for women isn’t good either. The miscarriage rate has risen by 1 percent per year over the last two decades (since 2000). If these trajectories continue, in vitro fertilization and other artificial reproductive technologies may become a widely needed tool for conceiving children.     In what year will male testosterone levels fall to half what they were on average in 1982?       In what year will miscarriages double from the number recorded in 2000?

The Dow Jones Industrial Average (DJIA) and the Standard & Poor's 500 (S&P 500) indexes are used as measures of overall movement in the stock market. The DJIA is based on the price movements of 30 large companies; the S&P 500 is an index composed of 500 stocks. Some say the S&P 500 is a better measure of stock market performance because it is broader based.

The Federal Bureau of Investigation reports state-level and national data on crimes.  An investigator compares the incidence of crime in the United States in 1991 and in 2001.  In 1991, there were 28,000 crimes compared with 22,000 in 2001.  Can you conclude that the US became more law-abiding over that time period?

You may need to use the appropriate appendix table or technology to answer this question. Advertisers contract with internet service providers and search engines to place ads on websites. They pay a fee based on the number of potential customers who click on their ad. Unforțunately, click fraud-the practice of someone clicking on an ad solely for the purpose of driving up advertising revenue–has become a problem. Businessweek reports that 4C percent of advertisers claim they have been a victim of click fraud. Suppose a simple random sample of 390 advertisers will be taken to learn more about how they are affected by this practice. (Round your answers to four decimal places.) (a) What is the probability that the sample proportion will be within ±0.04 of the population proportion experiencing click fraud? (b) What is the probability that the sample proportion will be greater than 0.45?

According to a New York Times/CBS poll, 76% agreed that it should be the government's responsibility to provide a decent standard of living for the elderly, and 35% agreed that it would be a good idea to invest part of their Social Security taxes on their own. What is the smallest percentage of people who could have agreed with both statements?

PART 2 The Angla Ruston University operates a Laundromat, solely for the purpose of providing laundering services to students in residence. You have been hired as accounting students to analyze the cost of the laundering services and develop a cost function which describes the behaviour of the laundering costs. The university administration has assembled the data for a twelve-month period pertaining to the monthly total costs of providing the service and the corresponding number of students who used the laundering facilities each month. You were recently taught how to use the Excel graphing tool and a member of the team successfully generated the scattergram given below from the data set provided.

When I was a student, I was one of a relative minority who worked in addition to going to classes.  That circumstance has changed drastically in the intervening years.  According to several recent studies, almost all students work at least part-time, and many work full-time while enrolled in classes (ACE Center for Policy and Analysis, 2006; Alfano and Eduljee, 2013; Perna, 2010).  Both faculty and administrators are concerned that the shift in focus to the world outside of school can affect academic performance.  We compare the GPA of students who work at least part-time outside of class with those who do not work.  What test should you use and why?

There is a looming crisis in universities and colleges across North America. In most places enrollments are increasing requiring more instructors. However, there are not enough PhDs to fill the vacancies now. Moreover, among current professors, a large proportion are nearing retirement age. On top of these problems, some universities allow professors over the age of 60 to retire early. To help devise a plan to deal with the crisis, a consultant surveyed 521 55- to 64-year-old professors and asked each whether he or she intended to retire before 65. The responses are 1=No and 2=Yes. Estimate with 95% confidence the proportion of professors who plan on early retirement. ONLY USE EXCEL AND PLEASE SHOW ALL STEPS AND EXCEL COMMANDS.

Government economic studies reveal that young adults, not middle-aged or older adults, are having the most difficult time in today’s economy. Although the nation’s labor market shows a decline in the unemployment rate, the percentage of young adults, ages 18 to 24, currently employed (54 percent) is at the lowest level since the government data collection began in 1948. If you were working for a national survey organization doing a general public survey of young adults and older adults, what topics and questions would you design into your survey to elaborate on this finding?
