( Round to two decimal places as needed . ) The population mean and standard deviation are given below. Find the required probability and determine whether the giv an would be considered unusual. For a sample of n = 66, find the probability of a sample mea less than 25.2 if H = 25 and a = 1.24. EFClick 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 = 65, the probability of a sample mean being less than 25.2 if u = 25 and a = 1.24 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 |than 5%%.
