In a clinical trial of a? vaccine, 12 comma 000
12,000 children were randomly divided into two groups. The subjects in group 1? (the experimental? group) were given the vaccine while the subjects in group 2? (the control? group) were given a placebo. Of the 6,000 children in the experimental? group, 79 developed the disease. Of the 6,000 children in the control? group, 106 developed the disease.
Determine whether the proportion of subjects in the experimental group who contracted the disease is less than the proportion of subjects in the control group who contracted the disease at the a=0.05 level of significance.
Determine the test statistic.
z0 = ?
Determine the p-value.
