For a sample of n = 75, the probability of a sample mean being greater than 222 if u =221 and o = 6.2 is (Round to four decimal places as needed.) Would the given sample mean be considered unusual? The sample mean be considered unusual because it V within the range of a usual event, namely within of the mean of the sample means.
