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 300 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)
