The National Health and Nutrition Examination Survey (NHANES) reported that in a recent year, the mean serum cholesterol level for U.S. adults was 202, with a standard deviation of 42 (the units are milligrams per deciliter). Suppose a random sample of 49 adults is taken and the mean cholesterol level is recorded.

What is the probability that the mean cholesterol level for the 49 adults is less than 190?

Round your answer to four decimal places.
