A1 Question 1 A powerful women's group has claimed that men and women differ in attitudes about sexual discrimination. A group of 50 men (group 1) and 40 women (group 2) were asked if they thought sexual discrimination is a problem in the United States. Of those sampled, 11 of the men and 19 of the women did believe that sexual discrimination is a problem. Find the value of the test statistic. Z = -2.55 Z = -0.85 Z = -1.05 Z = -1.20 Question 2 If we are testing for the difference between the means of 2 related populations with samples of n 1 = 20 and n 2 = 20, the number of degrees of freedom is equal to 39. 38. 19. 18. Question 3 Private colleges and universities rely on money contributed by individuals and corporations for their operating expenses. Much of this money is put into a fund called an endowment, and the college spends only the interest earned by the fund. A recent survey of 8 private colleges in the United States revealed the following endowments (in millions of rands): 60.2, 47.0, 235.1, 490.0, 122.6, 177.5, 95.4, and 220.0. What value will be used as the point estimate for the mean endowment of all private colleges in the United States? R1,447.8 R180.975 R143.042 R8 Question 4

TABLE 10-1 Are Japanese managers more motivated than American managers? A randomly selected group of each were administered the Sarnoff Survey of Attitudes Toward Life (SSATL), which measures motivation for upward mobility. The SSATL scores are summarized below. American Japanese Sample size 211 100 Mean SSATL Score 65.75 79.83 Population Std. Dev. 11.07 6.41 Referring to Table 10-1, judging from the way the data were collected, which test would likely be most appropriate to employ? Paired t test pooled-variance t test for the difference between two means F test for the ratio of two variances Z test for the difference between two proportions Question 5 TABLE 9-7 A major home improvement store conducted its biggest brand recognition campaign in the company's history. A series of new television advertisements featuring well- known entertainers and sports figures were launched. A key metric for the success of television advertisements is the proportion of viewers who "like the ads a lot." A study of 1,189 adults who viewed the ads reported that 230 indicated that they "like the ads a lot." The percentage of a typical television advertisement receiving the "like the ads a lot" score is believed to be 22%. Company officials wanted to know if there is evidence that the series of television advertisements are less successful than the typical ad (i.e. if there is evidence that the population proportion of "like the ads a lot" for the company's ads is less than 0.22) at a 0.01 level of significance. Referring to Table 9-7, the null hypothesis will be rejected if the test statistics is greater than 2.3263. less than 2.3263. greater than -2.3263.
