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, 126 of 669 subjects in the experimental group (group 1) experienced drowsiness as a side effect. After the second dose, 83 of 550 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? 10 Determine the null and alternative hypotheses. Ho: P P2 H: P P2 Find the test statistic for this hypothesis test. (Round to two decimal places as needed.) Atte Determine the P-value for this hypothesis test. (Round to three decimal places as needed.) Interpret the P-value. 0 If the population proportions are one would expect a sample difference proportion the one observed in about out of 1000 repetitions of this experiment. 0 0 (Round to the nearest integer as needed.) State the conclusion for this hypothesis test. 0 0 O A. Reject Ho. There is sufficient evidence to conclude 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. 0 of O B. Do not reject Ho. There is not sufficient evidence to conclude 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. 0 of
