Inrandomized, double-blind clinical trials of a newvaccine, children 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 seconddose, 102 of 693 subjects in the experimental group(group 1) experienced drowsiness as a side effect. After the seconddose, 59 of 574 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 =0.10 level ofsignificance?
