In a clinical trial of avaccine, 8,000children were randomly divided into two groups. The subjects in group 1(the experimentalgroup) were given the vaccine while the subjects in group 2(the controlgroup) were given a placebo. Of the 4,000children in the experimentalgroup, 86 developed the disease. Of the 4,000children in the controlgroup, 112 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 =0.10 level of significance.

Determine the test statistic.
