just the last part thank you!

Extracted text: In randomized, double-blind clinical trials of a new vaccine, infants were randomly divided into two groups. Subjects in group 1 received the new vaccine while subjects in group 2 received a control vaccine. After the second dose, 129 of 674 subjects in the experimental group (group 1) experienced drowsiness as a side effect. After the second dose, 86 of 555 of the subjects in the control group (group 2) experienced drowsiness as a side effect. Does the evidence suggest that a higher proportion of subjects in group 1 experienced drowsiness as a side effect than subjects in group 2 at the a = 0.10 level of significance? YA. The samples are independent. O B. The sample size is more than 5% of the population size for each sample. O c. The data come from a population that is normally distributed. O D. The samples are dependent. YE. The sample size is less than 5% of the population size for each sample. YF. n,pi (1-P1) 2 10 and nap2 (1-2) 2 10 Determine the null and alternative hypotheses. Họ: P1 = P2 H: P1 > P2 Find the test statistic for this hypothesis test. 1.67 (Round to two decimal places as needed.) Determine the P-value for this hypothesis test. 0.047 (Round three decimal places as needed.) Interpret the P-value. If the population proportions are (Round to the nearest integer as needed.) equal, one would expect a sample difference proportion greater than the one observed in about out of 1000 repetitions of this experiment.
