Workers and senior-level bosses were asked if it was seriously unethical to monitor employee e-mail. The results are summarized in the table to the right. Use a 0.05 significance level to test the claim that the response is independent of whether the subject is a worker or a boss. Yes No Workers 200 241 Bosses 43 81

A survey of 445 workers showed that 140 said it was unethical to monitor employee e-mail. When 110 senior-level bosses were surveyed, 41 said it was unethical to monitor employee e-mail. At the 10% significance level, do the data provide sufficient evidence to conclude that the proportion of workers that say monitoring employee e-mail is unethical is less than the proportion of bosses? Use the two-proportions z-test to conduct the required hypothesis test. Let population 1 be workers, and let...
