Suppose the average client charge per hour for out-ofcourt work by lawyers in the state

Suppose the average client charge per hour for out-ofcourt work by lawyers in the state of Iowa is $125. Suppose further that a random telephone sample of 32 lawyers in Iowa is taken and that the sample average charge per hour for out-of-court work is $110. If the population variance is $525, what is the probability of getting a sample mean of $110 or larger?
