An industrial/organizational psychologist wants to improve worker productivity for a client firm, but fırst he needs to gain a better understanding of the life of the typical white-collar professional. Fortunately, he has access to the 2008 Workplace Productivity Survey, commissioned by LexisNexis and prepared by WorldOne Research, which surveyed a sample of 650 white-collar professionals (250 legal professionals and 400 other professionals). One of the survey questions was, "During the average workday, how many hours do you spend attending meetings?" For the subsample of legal professionals (n = 250), the mean response was M = 2.0 hours, with a sample standard deviation of s = 5.1 hours. The estimated standard error is SM = 0.323. The psychologist can be 99% confident that the interval from 1.2 to includes the unknown population mean pu.
Westminster Financial has released a summary of investor and investment package information from the past fiscal year. During this time, Westminster provided a choice among 12 pre-designed investment packages. The investment packages were classified according to two variables: riskiness of investment package chosen ("Risky", "Moderate/mixed", and "Conservative") and age of investor ("Under 35", "35-49", or "50+"). Suppose that we're interested in the possible relationship between the age of the investor and the riskiness of the investment package the investor chose. The following contingency table gives a summary of the information released by Westminster regarding age and riskiness of investment package for 150 investors. In the cells of the table are the respective observed frequencies, and three of the cells also have blanks. Fill in these blanks with the frequencies expected if the two variables, riskiness of investment package chosen and age of investor, are independent. Round…

As part of their efforts, the executives also surveyed managers across the country to determinestaffing shortages. Managers were encouraged, but not required, to submit the survey. From theresponses they received, 45 out of 52 managers said they were either “severely understaffed” or“understaffed.” Looking at the numbers, one of the executives is outraged. “How can we expect ourstores to be successful if almost 87% are understaffed?” Give a statistical response tothe executive to assure them that the staffing problem is probably not as bad as it seemsin the preliminary numbers.
A cell phone service provider claims that only 1% of their calls get "dropped" (i.e., neither party hangs up, but the connection is lost). You work for the Consumer Protection Agency, and believe that the percent of dropped calls from this provider is higher than 1%. Your agency has been granted access to this company's detailed call records. It takes careful examination of each call transaction to determine if the call can be considered a "dropped call", so you are not able to easily calculate the actual percent of dropped calls directly from the entire database of millions of calls. So, you decide to take a random sample of 2500 calls, and each call is classified as "dropped" or "not dropped". Of the 2500 calls examined, 1.462% of them were classified as "dropped". Calculate the appropriate test statistic. Enter with 2 decimals (eg. 1.96).
A Harris Interactive poll reported that 32.4% of 275 randomly selected Americans living in the west stated that they attend church regularly. Whereas, 57.6% of 264 randomly selected Americans living in the south stated that they attend church regularly. Based on the results of this poll, can one reach the conclusion that the proportion of Americans who attend church regularly is lower in the west than in the south? Use ! = 5%.
A survey by the Arthur Andersen Enterprise attempted to determine what the leading challenges are for the growth and survival of small businesses. Although the economy and finding qualified workers were the leading challenges, several others were listed in the results of the study, including regulations, listed by 30% of the companies, and the tax burden, listed by 35%. Suppose that 71% of the companies listing regulations as a challenge also listed the tax burden as a challenge. Assume these percentages hold for all small businesses. 1. If a small business is randomly selected, find the following probabilities: (a) The small business lists either the tax burden or regulations as a challenge. (b) The small business lists either the tax burden or regulations but not both as a challenge. (c) The small business does not list regulations as a challenge given that it lists the tax burden as a challenge. (d) The small business does not list regulations as a challenge given that it does not…

Ask for question (c) and (d) Attempting to motivate customers to make early payment of bills, the manager of a consulting company offered customers an incentive to make early payment, a 20% discount for bills paid within 30 days of issuance of the bill. In order to assess the effect of the new policy on time to payment, the manager sampled 15 accounts and recorded the number of days to payment for the last bill issued under the old system and the first bill issued under the incentive system. The data, in days, are shown in the accompanying table: Bill Old System Incentive 1 92 28 2 88 30 3 65 29 4 85 85 5 95 29 6 64 28 7 65 26 8 62 29 9 90 88 10 89 30 11 65 70 12 75 30 13 84 27 14 90 92 15 80 29 a).

How Many Social Ties Do You Have? Most US adults have social ties with a large number of people, including friends, family, co-workers, and other acquaintances. It is nearly impossible for most people to reliably list all the people they know, but using a mathematical model, social analysts estimate that, on average, a US adult has social ties with 634 people.¹ A survey of 1700 randomly selected US adults who are cell phone users finds that the average number of social ties for the cell phone users in the sample was 664 with a standard deviation of 778. Does the sample provide evidence that the average number of social ties for a cell phone user is significantly different from 634, the hypothesized number for all US adults? ¹Hampton, K., Goulet, L., Rainie, L., and Purcell, K., "Social Networking Sites and Our Lives," Pew Research Center, pewresearch.org.
