Question 872379
Use the central limit theorem to find the mean and standard error of the means of the indicated sampling distribution. Then sketch a graph of the sampling distribution.
The per capita consumption of red meat by people in a country in a recent year was normally distributed, with a mean of 115 pounds and a standard deviation of 37.2 pounds. Random samples of size 20 are drawn from this population and the mean of each sample is determined.
-----
mean of sample means = 115 lbs.
standard error of sample means = 37.2/sqrt(20) = 8.32
