Problem 11E
Assume that the sample is taken from a large population and the eorrection factor can be ignored.
Serum Cholesterol LevelsThe 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 mean will be between 220 and 222 mg/dl. Assume the serum cholesterol level variable is normally distributed.

If a random sample of 35 overweight children is selected, find the probability that the mean will be between 220 and 222 mg/dl. Assume the serum cholesterol level variable is normally distributed.
ANSWER:
Solution:
Step 1 of 2:
The mean serum cholesterol level of a large population of overweight children is 220 milligrams per deciliter (mg/dl).
The standard deviation is 16.3 mg/dl.
A random sample of size 35 is randomly selected.
We have to find the probability that the mean will be between 220 and 222 mg/dl.
