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 = 31, find the probability of a sample mean being less than 12,750 or greater than 12,753 when u = 12,750 and o= 1.6. ..... For the given sample, the probability of a sample mean being less than 12,750 or greater than 12,753 is. (Round to four decimal places as needed.)
