5.4.17 Question Help 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 greater than 220 if u = 219 and 6 = 3.5. For a sample of n = 70, the probability of a sample mean being greater than 220 if u = 219 and o = 3.5 is (Round...
