- Use the central limit theorem to find the mean and standard error of the mean 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 116 pounds and a standard deviation of 39.7 pounds. Random samples of size 20 are drawn from this population and the mean of each sample is determined. %3D (Round to three decimal places as needed.) Sketch a graph of the sampling distribution.
