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 12,752 or greater than 12,755 when = 12,752 and σ = 2.2. For the given sample, the probability of a sample mean being less than 12,752 or greater than 12,755 is (Round to four decimal places as needed.)
