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 230 if u - 229 and o = 5.7 For a sample of n =65, the probability of a sample mean being greater than 230 if u = 229 and o = 5.7 is (Round to four decimal places as needed.) Would the given sample mean be considered unusual? The sample mean be considered unusual because it within the range of a usual event, namely within of the mean of the sample means
