The annual salary for one particular occupation is normally distributed, with a mean of about $133 comma 000 and a standard deviation of about $15 comma 000. Random samples of 28 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 mu Subscript x over bar equals nothing, and the standard deviation...
