Math Problem Statement
Find the mean and standard error of the mean of the sampling distribution. Then sketch a graph of the sampling distribution. The prices of photo printers on a website are normally distributed with a mean of $245 and a standard deviation of $66. Random samples of size 32 are drawn from this population and the mean of each sample is determined. Question content area bottom Part 1 The mean of the distribution of sample means is 245. Part 2 The standard deviation of the distribution of sample means is
