The population mean and standard deviation are given below. Find the indicated probability and determine whether the given sample mean would be considered unusual. For a sample of n = 31, find the probability of a sample mean being less than 12,748 or greater than 12,751 when μ = 12,748 and o=1.9. For the given sample, the probability of a sample mean being less than 12,748 or greater than 12,751 is (Round to four decimal places as needed.) C
