just the last part, thank you!

Extracted text: In 1945, 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 286 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 1945 survey and the recent survey who were total abstainers are 0.330 and 0.260 , respectively. (Round to three decimal places as needed.) (b) Has the proportion of adults who totally abstain from alcohol changed? Use the a = 0.10 level of significance. First verify the model requirements. Select all that apply. A. The sample size is less than 5% of the population size for each sample. O B. The data come from a population that is normally distributed. O c. The sample size is more than 5% of the population size for each sample. YD. n, Pi (1-P1) 2 10 and ng2 (1- P2) 2 10 YE. The samples are independent. O F. The samples are dependent. Identify the null and alternative hypotheses for this test. Let p, represent the population proportion of 1945 adults who were total abstainers and p, represent the population proportion of recent adults who were total abstainers. Determine the null and alternative hypotheses. Ho: P1 = P2 H: p1 # P2 Find the test statistic for this hypothesis test. (Round to two decimal places as needed.)
