Bopulation proportion of 1943 adults who were total abstainers and p, represent the population proportion of recent adults Determine the null and alternative hypotheses. Ho P1 V P2 H P1 V P2 Find the test statistic for this hypothesis test. (Round to two decimal places as needed.) Determine the P-value for this hypothesis test.

If the population proportions are one would expect a sample difference proportion V the one observed in about out of 100 repetitions of this experim (Round to the nearest integer as needed.) State the conclusion for this hypothesis test. O A. Do not reject Ho. There is sufficient evidence at the a= 0.05 level of significance to suggest the proportion of adults who totally abstain from alcohol has changed. O B. Do not reject Ho. There is not sufficient evidence at the a = 0.05 level of significance to suggest the proportion of adults who totally abstain from alcohol has changed. O C. Reject Ho. There is not sufficient evidence at the a = 0.05 level of significance to suggest the proportion of adults who totally abstain from alcohol has changed. O D. Reject Ho. There is sufficient evidence at the a =0.05 level of significance to suggest the proportion of adults who totally abstain from alcohol has changed.

In 1943, an organization surveyed 1100 adults and asked, "Are you a total abstainer from, or do you on occasion consume, alcoholic beverages?" Of the 1100 adults surveyed, 429 indicated that they were total abstainers. In a recent survey the same question was asked of 1100 adults and 374 indicated that they were total abstainers. Complete parts (a) and (b) below. (a) Determine the sample proportion for each sample. The proportions of the adults who took the 1943 survey and the recent survey who were total abstainers are and respectively. (Round to three decimal places as needed (b) Has the proportion of adults who totally abstain from alcohol changed? Use the a=0.05 level of significance. First verify the model requirements.
