The annual salary for one particular occupation is nornmally distributed, With a mean of about $125,000 and a standard deviation of about $22,000. Random samples of 27 are drawn from this population, and the mean of each sample is determined. Find the mean and standard deviation of the sampling distribution of these sample means. Then, sketch a graph of the sampling distribution. The mean is u; =, and the standard deviation is (Round to the nearest integer as needed. Do not include the $ symbol in your answers.)
