The mean serum cholesterol level of a large population of overweight children is
220 milligrams per deciliter (mg/dl), and the standard deviation is 16.3 mg/dl. If a

random sample of 35 overweight children is selected, find the probability that the

sample mean will be between 220 and 222 mg/dl. Assume the serum cholesterol

level variable is normally distributed.
