Question

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, 363 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 $alpha = 0.05$ level of significance. Determine the null and alternative hypotheses. Choose the correct answer below. A. $H_0: p_1 = p_2$ versus $H_1: p_1 > p_2$ B. $H_0: p_1 = p_2$ versus $H_1: p_1 eq p_2$ C. $H_0: p_1 = 0$ versus $H_1: p_1 eq 0$ D. $H_0: p_1 = p_2$ versus $H_1: p_1 < p_2$ The test statistic $z_0$ is _. (Round to two decimal places as needed.) The P-value is _. (Round to three decimal places as needed.) What is the result of this hypothesis test? A. Reject the null hypothesis because there is sufficient evidence to conclude that the proportion of adults who totally abstain from alcohol has changed at the $alpha = 0.05$ level of significance.

surveyed, 363 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 $alpha = 0.05$ level of significance.
Determine the null and alternative hypotheses. Choose the correct answer below.
A. $H_0: p_1 = p_2$ versus $H_1: p_1 > p_2$
B. $H_0: p_1 = p_2$ versus $H_1: p_1 
eq p_2$
C. $H_0: p_1 = 0$ versus $H_1: p_1 
eq 0$
D. $H_0: p_1 = p_2$ versus $H_1: p_1 < p_2$
The test statistic $z_0$ is _____. (Round to two decimal places as needed.)
The P-value is _____. (Round to three decimal places as needed.)
What is the result of this hypothesis test?
A. Reject the null hypothesis because there is sufficient evidence to conclude that the proportion of adults who totally abstain from alcohol has changed at the
$alpha = 0.05$ level of significance.
