The annual salary.r for one particular occupation is normally distributed. with a mean of about $135.000 and a standard deviation of about 820.000. Random samples of 3? are drawn from this population. and the mean of each sample is determined. Find the mean and standard deviation ofthe sampling distribution ofthese sample means. Then: sketch a graph of the sampling distribution. The mean is pi = = and the standard deviation is 5i = [Round to the nearest integer as needed. Do not include the $ symbol in your answers.)
