The director of the IRS has been flooded with complaints that people must wait more than 40 minutes before seeing an IRS representative.

The average waiting time for the sample is 60 minutes with a standard deviation of 22 minutes. (a) Is there overwhelming evidence to support the claim that the wait time to see an IRS representative is more than 40 minutes at a 0.100 significance level?
