- The following information applies to questions 34 and 35. Assume that driving skill, S, varies throughout the population. Automobile insurers classify drivers into two categories: “Good” and “Bad”. Good drivers are those people who have driving skills above a threshold level of driving skill, S*. Bad drivers, on the other hand, have driving skills that fall below the threshold level, S*. Good drivers pay lower rates than Bad drivers. Additionally, assume that it’s common knowledge that Welsh are more skillful drivers than Scots, such that a higher proportion of the Welsh population has driving skills above S* than the Scottish population. Also assume that there is a law that prohibits insurers from learning a person’s driving skill. Which group would be most likely to invest in a lobbying campaign supporting a law that would prohibit the use of these new data collection devices? A. Welsh with driving skills greater than S* B. Scots with driving skills…CASE STUDY: #2 In August 2000, a young woman from Gozo, an island south of Italy, discovered that she was carrying conjoined twins. Knowing that health-care facilities on Gozo were inadequate to deal with the complications of such a birth, she and her husband went to St. Mary’s Hospital in Manchester, England, to have the babies delivered. The infants, known as Mary and Jodie, were joined at the lower abdomen. Their spines were fused, and they had one heart and one pair of lungs between them. Jodie, the stronger one, was providing blood for her sister. No one knows how many sets of conjoined twins are born each year, but the number has been estimated at 200. Most die shortly after birth, but some conjoined twins do well. They grow to adulthood and marry and have children themselves. But the outlook for Mary and Jodie was grim. The doctors said that without intervention the girls would die within six months. The only hope was an operation to separate them. This would save Jodie, but…QUESTION 35 The following information applies to questions 34 and 35. Assume that driving skill, S, varies throughout the population.

- Provide an analysis of the evidence emerging from tables 1 and 2.A government study found that people who eat chocolate frequently weighless than people who don’t. Researchers questioned 1000 individuals fromCalifornia between the ages of 20 and 85 about their eating habits, andmeasured their weight and height. On average, participants ate chocolatetwice a week and had a body mass index (BMI) of 28. There was anobserved difference of five to seven pounds in weight between those whoate chocolate five times a week and those who did not eat any chocolate atall, with the chocolate eaters weighing less on average. Frequent chocolateeaters also consumed more calories, on average, than people who consumedless chocolate. Based on this summary, would you recommend thatAmerican’s who do not presently eat chocolate, consider eating chocolateup to five times a week if they want to lose weight? Why or why not?Explain.States (and provinces) that have control over taxation sometimes reduce taxes in an attempt to spur economic growth.

- how is the statment a good example of why qualitative methodologie is more valuable in advancing cross-cultural research? I think qualitative methodologies are very valuable in advancing cross-cultural research. Qualitative methodologies are used in cross-cultural research by cultural anthropologist for what are called ethnographies. Ethnographies involve observation and field-work within the cultural context and require descriptive qualitative analysis. Some of the advantages of studies involving two or three countries compared to studies that involve ten or more countries are a more concentrated and have a smaller study group. Another advantage is being able to report various cultural variables as it relates to the study and qualitative data. A few disadvantages of studies involving two or three countries compared to involving ten or more countries are the potential for inaccurate results if it does not include the entire population. Another disadvantage of three countries in a study…Explain the term multicolllinearity18.

- The Ames Riders, a women’s professional basketball team, employs a head coach and two assistant coaches. The total number of employees of the team (including players) is 20. The head coach, a male, is known for his off-color sense of humor. He has been known to make remarks to the two assistant coaches regarding their marital and sex lives. This activity has not been frequent, but it has occurred more than once. However, there has been no evidence of any other acts and no evidence that the assistant coaches suffered in their employment. Each has been with the team for five years and has received raises and bonuses in each year of employment with the Riders. Both of the assistant coaches have complained to you (a group who ensures that the team uses proper workplace practices). You, the members of the committee, have to decide on the following: Did sex discrimination occur? Why or why not? Did sexual harassment occur? Why or why not? What actions would you take against the head coach…Below is the abstract of a recentNational Bureau of Economic Research working paper entitled “Human capital and organizational performance: evidence from the health care sector” by Ann Bartel, Ciaran Phibbs, Nancy Beaulieu, and Patricia Stone (2011): This paper contributes to the literature on the relationship between human capital and organizational performance. We use detailed longitudinal monthly data on nursing units in the Veterans Administration hospital system to identify how the human capital (general, hospital-specific and unit or team-specific) of the nursing team on the unit affects patients’ outcomes. Since we use monthly, not annual, data, we are able to avoid the omitted variable bias and endogeneity bias that could result when annual data are used. Nurse staffing levels, general human capital, and unit-specific human capital have positive and significant effects on patient outcomes while the use of contract nurses, who have less specific capital than regular staff…Which of the following should not be included in the group (criteria for evidence)?
