Example 6.48 Suppose that we are interested in estimat- ing the prevalence rate of the breast cancer among 50- to 54-year old women whose mothers have had breast cancer. Suppose that in a random sample of 10,000 such women, 400 are found to have had breast cancer at some point in their lives. How can an interval estimate of the parame- ter p, the percentage of the women with breast cancer, be obtained?
