Question 872379: 18. 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.
You can put this solution on YOUR website! 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.

-----
mean of sample means = 115 lbs.
standard error of sample means = 37.2/sqrt(20) = 8.32
