The average cholesterol level for women in the UnitedStates is 209.4 mg/dl (milligrams per deciliter) with astandard deviation of 42.9 mg/dl. The Center for DiseaseControl (CDC) considers cholesterol levels less than 200mg/dL to be be 'normal'.What proportion of US women have cholesterol levels thatare considered 'normal'?Assume the cholesterol levels of women can be describedby a Normal distribution.0.5000.0750.5870.413
