Lotal abstalner from, or do you on occasion consume, alcoholic beverages?" Of the 1,100 adults surveyed, 362 indicated that they were total abstainers. Sixty years later, the same question was asked of 1,100 adults and 396 indicated that they were total abstainers. Has the proportion of adults who totally abstain from alcohol changed? Use the a=0.05 level of significance. Determine the null and alternative hypotheses. Choose the correct answer below. O A. Ho: P1 = P2 versus H,: P1 P2 OC. Ho: P1 = P2 versus H,: p1 #P2 O D. Ho P1 =0 versus H,: P1 #0 The test statistic z, is - 1.53 . (Round to two decimal places as needed.) The P-value is (Round to three decimal places as needed.)

should we reject or do not reject the null hypothesis?

An organization surveyed 1,100 adults and asked, "Are you a total abstainer from, or do you on occasion consume, alcoholic beverages?" Of the 1,100 adults surveyed, 362 indicated that they were total abstainers. Sixty years later, the same question was asked of 1,100 adults and 396 indicated that they were total abstainers. Has the proportion of adults who totally abstain from alcohol changed? Use the a = 0.05 level of significance. Determine the null and alternative hypotheses. Choose the correct answer below. O A. Ho P1 = P2 versus H P1 <P2 O B. Ho P, =P2 versus H, P, >P2 C. Ho P1 =P2 versus H, p, P2 O D. Ho p, = 0 versus H, p, 70 The test statistic z, is - 1.53. (Round to two decimal places as needed) The P-value is (Round to three decimal places as needed.)
