In 1941, an organization surveyed 1100 adults and asked, "Are you a total abstainer from, or do you on occasionconsume, alcoholic beverages?" Of the 1100 adults surveyed, 374 indicated that they were total abstainers. In a recentsurvey, the same question was asked of 1100 adults and 341 indicated that they were total abstainers.

You may need to use the appropriate appendix table or technology to answer this question. Consider the hypothesis test. Ho: P1 - P2 0 The following results are for independent samples taken from the two populations. Sample 1 Sample 2 n1 = 200 n2 = 300 = 0.24 P2 P1 = 0.16 (a) Calculate the test statistic. (Round your answer to two decimal places.) What is the p-value? (Round your answer to four decimal places.) p-value (b) With a = 0.05, what is your hypothesis testing conclusion? Reject Ho. There is insufficient evidence to conclude that p, - p2 > 0. Reject Ho. There is sufficient evidence to conclude that p, - p, > 0. Do not reject Ho. There is insufficient evidence to conclude that p, - p, > 0. Do not Reject Ho: There is sufficient evidence to conclude that p, - p, > 0.
We are collecting data on the patients that have been vaccinated for the coronavirus, and the initial data shows a 90% success. We want the margin of error to be no more than 3%. We want to be extremely careful, so we are going to use a 99% confidence. Determine the smallest size of the sample to achieve this level of confidence. a 560 b 680 c 664 d 600 e 686
