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 216 if u = 215 and o = 3.6. For a sample of n = 65, the probability of a sample mean being greater than 216 if p = 215 and o = 3.6 is (Round to four decimal places as needed.)
