Reference no: EM13105191

Borst et.al. investigated the relation of ego development, age, gender, and diagnosis to suicidality among adolescent psychiatric inpatients. Their sample consisted of 96 boys and 123 girls between the ages of 12 and 16 years selected from admissions to a child and adolescent unit of a private psychiatric hospital. Suicide attempts were reported by 18 of the boys and 60 of the girls. Assume that the girls (the boys) behave like a simple sample from a population of similar girls (similar boys). Construct 99% confidence interval for the difference between the proportions of suicide attempters. Make your conclusion based on the confidence interval.
