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, 117 of 750 subjects in the experimental group (group 1) experienced drowsiness as a side effect. After the second dose, 74 of 631 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 = 0.05 level of significance? Determine the P-value for this hypothesis test. (Round to three decimal places as needed.) Interpret the P-value. If the population proportions are one would expect a sample difference proportion V the one observed in about out of 1000 repetitions of this experiment. (Round to the nearest integer as needed.) State the conclusion for this hypothesis test. 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. 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 = 0.05 level of significance. O C. Reject Ho. There is not sufficient evidence to conclude that a higher proportion of subjects in 1 experienced drowsiness as a side effect than subjects in group 2 at the a = 0.05 level of significance. O D. 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.

Transcribed Image Text: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, 117 of 750 subjects in the experimental group (group 1) experienced drowsiness as a side effect.
After the second dose, 74 of 631 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 = 0.05 level of significance?
Determine the P-value for this hypothesis test.
(Round to three decimal places as needed.)
Interpret the P-value.
If the population proportions are
one would expect a sample difference proportion
the one observed in about
out
of 1000 repetitions of this experiment.
(Round to the nearest integer as needed.)
State the conclusion for this hypothesis test.
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.
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 = 0.05 level of significance.
O c. 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. 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.
