Assume the hourly wage rate for a fast-growing online job is normally distributed with a mean of =$24.90.. Suppose a random sample of n=25 workers revealed a mean wage of x=$23.95 and a standard deviation of s=$1.45.

At =0.025, is there enough evidence to conclude that the mean hourly wage is less than $24.90?
