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 u = 22 and σ = 1.31. For a sample of n = 70, the probability of a sample mean being less than 22.1 if µ = 22 and σ=1.31 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%.
