An organization surveyed 1 comma 100 adults and asked, "Are you a total abstainer from, or do you on occasion consume, alcoholic beverages?" Of the 1 comma 100 adults surveyed, 360 indicated that they were total abstainers. Sixty years later, the same question was asked of 1 comma 100 adults and 435 indicated that they were total abstainers. Has the proportion of adults who totally abstain from alcohol changed? Use the alpha equals 0.05 level of significance. Determine the null and alternative hypotheses. Choose the correct answer below. A. Upper H 0 : p 1 equals p 2 versus Upper H 1 : p 1 greater than p 2 B. Upper H 0 : p 1 equals 0 versus Upper H 1 : p 1 not equals 0 C. Upper H 0 : p 1 equals p 2 versus Upper H 1 : p 1 less than p 2 D. Upper H 0 : p 1 equals p 2 versus Upper H 1 : p 1 not equals p 2 The test statistic z 0 is nothing. (Round to two decimal places as needed.) The P-value is nothing. (Round to three decimal places as needed.) What is the result of this hypothesis test? A. Do not 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 equals 0.05 level of significance. B. Reject the null hypothesis because there is not sufficient evidence to conclude that the proportion of adults who totally abstain from alcohol has changed at the alpha equals 0.05 level of significance. C. Do not reject the null hypothesis because there is not sufficient evidence to conclude that the proportion of adults who totally abstain from alcohol has changed at the alpha equals 0.05 level of significance. D. 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 equals 0.05 level of significance.
