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, 134 of 460 subjects in the experimental group (group 1) experienced drowsiness as a side effect. After the second dose, 26 of 84 of the subjects in the control group (group 2) experienced drowsiness as a side effect. Does the evidence suggest that a different proportion of subjects in group 1 experienced drowsiness as a side effect than subjects in group 2 at the $\alpha=0.01$ level of significance?
Determine the null and alternative hypotheses. Choose the correct answer below. A. $H_{0}: p_{1}=p_{2}$ versus $H_{1}: p_{1}<p_{2}$ B. $H_{0}: p_{1}=0$ versus $H_{0}: p_{1} \neq 0$ C. $H_{0}: p_{1}=p_{2}$ versus $H_{1}: p_{1} \neq p_{2}$ D. $H_{0}: p_{1}=p_{2}$ versus $H_{1}: p_{1}>p_{2}$
