In randomized, double-blind clinical trials of a new vaccine, ratsrats 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, 106106 of 503503 subjects in the experimental group (group 1) experienced drowsinessdrowsiness as a side effect. after the second dose, 8787 of 602602 of the subjects in the control group (group 2) experienced drowsinessdrowsiness as a side effect. does the evidence suggest that a higher proportion of subjects in group 1 experienced drowsinessdrowsiness as a side effect than subjects in group 2 at the alphaαequals=0.050.05 level of significance?
