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 = 75, find the probability of a sample mean being greater than 223 if μ = 222 and a = 6.1.
For a sample of n = 75, the probability of a sample mean being greater than 223 if μ-222 and a = 6.1 is
(Round to four decimal places as needed.)
