were total abstainers. Complete parts (a) and (b) below. In 1950, 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, 363 indicated that they were total abstainers. In a recent survey, the same question was asked of 1100 adults and 319 indicated that they (a) Determine the sample proportion for each sample. The proportions of the adults who took the 1950 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 = 0.01 level of significance. First verify the model requirements. Select all that apply. A. The sample size is more than 5% of the population size for each sample. B. The samples are dependent. DC. The samples are independent. D D. nip1 (1-P1 ) 2 10 and n2p2 (1 - P2) 2 10 E. The data come from a population that is normally distributed. )F. The sample size is less than 5% of the population size for each sample. Identify the null and alternative hypotheses for this test. Let p, represent the population proportion of 1950 adults who were total abstainers and P2 represent the population proportion of recent adults who were total abstainers. Determine the null and alternative hypotheses. Ho:P1 = P 2 H 1 : P1 > P2 Find the test statistic for this hypothesis test . (Round to two decimal places as needed.) Determine the P-value for this hypothesis test. (Round to three decimal places as needed.) Interpret the P-value. If the population proportions are equal, one would expect a sample difference proportion greater than the one observed in about | out of 100 repetitions of this experiment. ( Round to the nearest integer as needed.) State the conclusion for this hypothesis test. A. Do not reject Ho. There is not sufficient evidence at the a = 0.01 level of significance to suggest the proportion of adults who totally abstain from alcohol has changed. B. Reject Ho. There is sufficient evidence at the a = 0.01 level of significance to suggest the proportion of adults who totally abstain from alcohol has changed. C. Do not reject Ha. There is sufficient evidence at the a = 0.01 level of significance to suggest the proportion of adults who totally abstain from alcohol has changed. Next LG
