In a study initiated in 1940, a research group followed the lives of 200 Harvard graduates and 400 inner-city, working-class men from Boston and Cambridge. Massachusetts. Eventually, 26 from the Harvard group and 110 from the inner-city, working-class group became alcoholics. Assume that these are random samples from the collection of Harvard graduates and inner-city, working-class men from Boston and Cambridge.
(a) Find a 95% confidence interval for the proportion p of Harvard graduates who eventually became alcoholics.
(b) Find a 95% confidence interval for the proportion p of the inner-city, working-class group who eventually became alcoholics.
