In randomized, double-blind clinical trials of a new vaccine, monkeys 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, 124 of 736 subjects in the experimental group (group 1) experienced drowsiness as a side effect. After the second dose, 81 of 617 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 = 0.01 level of significance? Verify the model requirements. Select all that apply. O A. The data come from a population that is normally distributed. YB. The samples are independent. YC. The sample size is less than 5% of the population size for each sample. n,p, (1-P) 2 10 and nê2 (1-P2) 2 10 O E. The samples are dependent. O F. The sample size is more than 5% of the population size for each sample. Determine the null and alternative hypotheses. Ho: P1 = P2 H:P, > P2 Find the test statistic for this hypothesis test. 0.05 (Round to two decimal places as needed.)
