The population mean and standard deviation are given below. Find the required probability and determine whether the given sample mean would be considered unusual. For a sample of n = 65, find the probability of a sample mean being greater than 215 if u = 214 and o = 5.6. For a sample of n = 65, the probability of a sample mean being greater than 215 if u = 214 and o = 5.6 is (Round to four decimal places as needed.)
