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 = 70, find the probability of a sample mean being less than 22.1 if = 22 and = 1.31. Click the icon to view page 1 of the standard normal table. Click the icon to view page 2 of the standard normal table. For a sample of n = 70, the probability of a sample mean being less than 22.1 if = 22 and = 1.31 is 0.7389. (Round to four decimal places as needed.) Would the given sample mean be considered unusual? The sample mean be considered unusual because it has a probability that is than 5%.
