3. The measurement of blood cholestrol levels (in milligrams per deciliter or mg/DI) shows desirable ragne at less than 200mg/dL, borderline high-risk range at 200-239 mg/dL, and high risk range at or above 240mg/dL. A hospital recorded that their patients have a variation of 15.25 mg/dL blood cholestrol level. A random sample of 50 patients is selected from the hospital, and the sample mean of blood cholestrol level is determined to be 198 mg/dL. A.
