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, 107 of 676 subjects in the experimental group (group 1) experienced fever as a side effect. After the second dose, 64 of 557 of the subjects in the control group (group 2) experienced fever as a side effect. Does the evidence suggest that a higher proportion of subjects in group 1 experienced fever as a side effect than subjects in group 2 at the a= 0.10 level of significance? Verify the model requirements. Select all that apply. A. The samples are dependent. B. The samples are independent. C. The data come from a population that is normally distributed. D. The sample size is less than 5% of the population size for each sample. E. ₁₁ (1-₁) ≥ 10 and n₂P₂ (1-₂) ²10 OF. The sample size is more than 5% of the population size for each sample.
