Cholesterol levels for women aged 20 to 34 follow an approximately normal distribution with mean 185 milligrams per deciliter (mg/dl). Women with cholesterol levels above 220 mg/dl are con- sidered to have high cholesterol and about 18.5% of women fall into this category. What is the standard deviation of the distribution of cholesterol levels for women aged 20 to 34?

Cholesterol levels for women aged 20 to 34 follow a normal distribution with mean 185 milligrams per deciliter (mg/dl) and standard deviation 40 mg/dl. What is the probability of randomly selecting a woman in this age range with a cholesterol level below 140 mg/dl? Note: As always, please give this probability in decimal form (i.e., 0.xxx).
