The population mean and standard deviation are given below. Find required probability and determine whether the given sample would be considered unusual

for a sample of n=66, find the probability of sample mean being less than 23.2 if mean=23 and sigma=1.22

For sample of n=66, the probability of a sample mean being less than 23.2 if mean = 23 and sigma=1.22 is

Would the given sample mean be considered unusual?

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