just the multiple choice question thank you!

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.
Or Tne sampies are depenuenit.
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
H1: P1 # P2
Find the test statistic for this hypothesis test.
3.60 (Round to two decimal places as needed.)
Determine the P-value for this hypothesis test.
0.000 (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 absolute value of the one observed in about 0 out of 100 repetitions of this experiment.
(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 = 0.10 level of significance to suggest the proportion of adults who totally abstain from alcohol has changed.
O B. Reject Ho. There is not sufficient evidence at the a = 0.10 level of significance to suggest the proportion of adults who totally abstain from alcohol has changed.
Oc. Reject Ho. There is sufficient evidence at the a = 0.10 level of significance to suggest the proportion of adults who totally abstain from alcohol has changed.
O D. Do not reject Ho. There is not sufficient evidence at the a = 0.10 level of significance to suggest the proportion of adults who totally abstain from alcohol has changed.
