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=64?, find the probability of a sample mean being less than 20.6 if ?=21 and ?=1.25.

For a sample of n=64?, the probability of a sample mean being less than 20.6 if ?=21 and ?=1.25 is (Round to four decimal places as? needed.)

Would the given sample mean be considered? unusual?

The sample mean ? would or would not be considered unusual because it has a probability that is ? greater or less than? 5%.
