the cholesterol level of men in the united states are normally distributed, with a mean = 215 milligrams per deciliter and a standard deviation = 25 milligrams per deciliter.
if a man is randomly selected, what is the probability that his cholesterol level is more than 245?
based on your answer to #1, would you consider it unusual for a man to have a cholesterol level of 245? Why?
what cholesterol level cuts off the lower 10% of levels
