The serum cholesterol level of U.S. females 20 years old or older is normally distributed with a mean of 200 mg/dL (milligrams per deciliter) and a standard deviation of 44 mg/dL. Let X represent serum total cholesterol level for U.S. females 20 years old or older. One outcome of interest is the probability that a woman has a serum cholesterol level greater than 266 mg/dL. If 400 U.S. women 20 yrs old or older are randomly selected, how many of them would we expect to have a serum cholesterol level greater than 266 mg/dL? Choose the closest value. (Hint: calculate the probability of interest first)
A. 0.9332
B. 27
C. 0.0668
D. 374
