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 = 63, find the probability of a sample mean being less than 19.5 if u = 20 and o=1.33. 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 = 63, the probability of a sample mean being less than 19.5 if u = 20 and σ = 1.33 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%.
