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 ~= 6?, nd the probability of a sample mean being less than 21.5 it'p. = 22 and :3 =1.25. a Click the icon to View page 1 of the standard normal table. a Click the icon to View page 2 of the standard normal table. For a sample of n = 6?, the probability of a sample mean being less than 21.5 if p. = 22 and a: 1.25 is (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 El than 5%
