In Exercises 53 and 54, use the Central Limit Theorem to find the mean and standard deviation of the indicated sampling distribution of sample means. Then
sketch a graph of the sampling distribution.
53. The annual per capita consumption of citrus fruits by people in the
United States is normally distributed, with a mean of 85.6 pounds and a
standard deviation of 20.5 pounds. Random samples of size 35 are drawn
from this population, and the mean of each sample is determined. (Adapted
