Use the Central Limit Theorem to find the mean and standard error of the mean of the sampling distribution. Then sketch a graph of the sampling distribution. The mean price of photo printers on a website is $225 with a standard deviation of $63. Random samples of size 20 are drawn from this population and the mean of each sample is determined. The mean of the distribution of sample means is.
