In randomized, double-blind clinical trials of a new vaccine, rats 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, 104 of 699 subjects in the experimental group (group 1) experienced drowsiness as a side effect. After the second dose, 61 of 580 of the subjects in the control group (group 2) experienced drowsiness as a side effect. Does the evidence suggest that higher proportion of subjects in group 1 experienced drowsiness as a side effect than subjects in group 2 at the a= 0.05 level of significance? 2.32 (Round to two decimal places as needed.). Determine the P-value for this hypothesis test. 0.010 (Round to three decimal places as needed.) Interpret the P-value. If the population proportions are (Round to the nearest integer as needed.) State the conclusion for this hypothesis test. one would expect a sample difference proportion CCIDE the one observed in about out of 1000 repetitions of this experiment. OA. Reject Ho. There is sufficient evidence to conclude that. higher proportion of subjects in group 1 experienced drowsiness as a side effect than subjects in group 2 at the a= 0.05 level of significance. OB. 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=0.05 level of significance OC. 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= 0.05 level of significance OD. 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= 0.05 level of significance.

After the second dose, 61 of 580 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 α = 0.05 level of significance? 2.32 (Round to two decimal places as needed.) Determine the P-value for this hypothesis test. 0.010 (Round to three decimal places as needed.) Interpret the P-value. If the population proportions are (Round to the nearest integer as needed.) State the conclusion for this hypothesis test. one would expect a sample difference proportion the one observed in about out of 1000 repetitions of this experiment. 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= 0.05 level of significance. OB.

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= 0.05 level of significance O D.
