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. YA. 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. D. n,Pi (1-P1) 2 10 and n2(1-P2) 2 10 VE. The samples are independent. OF. 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 p2 represent the population proportion of recent adults who were total abstainers. Determine the null and alternative hypotheses. Họ: P1 - P2 H: 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.

just the last part 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.
YA. 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.
D. niPi (1-P1) 2 10 and nP2 (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.

Interpret the P-value.
If the population proportions are
equal,
one would expect a sample difference proportion
V the one observed in about
out of 100 repetitions of this experiment.
