omized, double-blind clinical trials of a new vaccine, infants were randomly divided 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? LE nPi (1-P1) 2 10 and ny2 (1-P2) 2 10 Determine the null and alternative hypotheses. Ho: 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 to three decimal places as needed.) Interpret the P-value. this experiment. 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 47 out of 1000 repetitions State the conclusion for this hypothesis test. O A. 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. O B. 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. OC. Do not 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. O D. 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.
