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 nequals

=62

62, find the probability of a sample mean being less than 22.9

22.9 if mu

equals

=23 and sigma, equals=1.33 For a sample of n equals

=62

62, the probability of a sample mean being less than 22.9

22.9 if mu equals 23

=23 and sigma

equals

1.33 is ?
