A health insurance company in country A sells policies to tourists who intend to visit the US for less than 3 months. To limit its financial exposure, it requires applicants to undertake a physical examination and meet specified criteria for different tests. To simplify the problem, let us assume that only one test is done and it measures cholesterol level of the applicant. Historical records in country A indicate that cholesterol level is normally distributed with a mean of 225 milligrams per deciliter (mg/dL) and a standard deviation of 39.5 mg/dL. High cholesterol levels increase the risk of a cardiovascular incident, for which the company may need to make major insurance payouts. The premium charged is a flat $3000/person for those who qualify. For planning purposes, assume the company will get 100,000 applications in a particular year.
