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 $227 with a standard deviation of $58. Random samples of size 22 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 enter your response here . Part 2 The standard deviation of the distribution of sample means is enter your response here . (Type an integer or decimal rounded to three decimal places as needed.)
