Q : A study of teenage suicide included a sample of 96 boys and 123 girls selected

scientifically from admissions records to a private psychiatric hospital. Suicide attempts were

reported by 18 of the boys and 60 of the girls. We assume that the girls constitute a simple

random sample from a population of similar girls and likewise for the boys. Construct a 99

percent confidence interval for the difference between the two population proportions. What

would be your conclusion if we say boys are more inclined to suicides.
