Clinical Trial: The drug Prevnar is a vaccine meant to prevent certain types of bacterial meningitis. It is typically administered to infants staring around two months of age. In randomized double-blind clinical trials of Prevnar, infants were randomly divided into two groups: Group 1 (experimental group): subjects received Prevnar Group 2 (control group): subjects received a control vaccine (placebo) After the rst dose 107 of 710 subjects in the experimental group experienced fever as a side effect. After the rst dose, 67 of 611 subjects in the control group experienced fever as a side effect. Test the claim that the proportion of subjects who experienced fever as a side effect are different. Use a = 0.05 significance level. Let: p1 = proportion of subjects in the experimental group who experienced fever as a side effect. p2 = proportion of subjects in the control group who experienced fever as a side effect. Perform the hypothesis test, using the 5-step process: a) Let Ho: p1 = p2 . State H1 in symbols only. Identify which hypothesis is the claim and determine the type of test (right-tail, left-tail, two tail). b) Determine the critical values and label it -- for example, 2 = 1.96 ort = -2.421, etc). c) Compute the test value. If you are using the p-value method, then include the p-value of the test. d) Make the decision to Reject H0 or Do not reject Ho. e) State your complete conclusion in the context of the claim
