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

67, find the probability of a sample mean being less than 25.3

25.3 if mu

equals

25 and sigma

equals

=1.26

67, the probability of a sample mean being less than 25.3

25.3 if mu equals 25

(Round to four decimal places as needed.)

Would the given sample mean be considered unusual?

The sample mean

would

would not

be considered unusual because it has a probability that is

greater

less

than 5%.
