A survey of 455 workers showed that 160 said it was unethical to monitor employee e-mail. When 100 senior-level bosses were surveyed, 45 said it was unethical to monitor employee e-mail. At the 1% 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 population 2 be bosses. What are the hypotheses for this test? O A. Ho: P1 =P2, Ha: P1 < P2 O B. Ho: P1 = P2., Ha: P1> P2 OC. Ho: P1 >P2. Ha P1 = P2 O D. Ho: P1 = P2, H: P1P2 O E. Ho: P1
