The population mean and standard deviation are given below. Find the indicated probability and determine whether a sample mean in the given range below would be considered unusual. If convenient, use technology to find the probability. For a sample of n = 38, find the probability of a sample mean being less than 12,748 or greater than 12,751 when u = 12,748 and o = 1.1. 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.)
