A state department of transportation claims that the mean wait time for various services at its different locations is approximately 6 mins. A random sample of 26 services at different locations has a mean wait time of 10.3 minutes and a standard deviation of 8.0 mins. Is there enough evidence to show that the wait time is more than the claim. Use 1% level of significance?
What is the Null hypothesis (H0); Alternate hypothesis (H1); and the direction of the test?
Which distribution is used in this case?
What is the critical value?
What is the Test Statistic Value?
What is the P-value?
What is the conclusion of the test?

To promote its services, a walk-in medical clinic claims that
the mean waiting time required for patients to see a doctor is
15minutes or less. To investigate this claim, a local consumer
agency sent a sample of 36 “sick” people to the clinic. These
people had to wait, on average, 20 minutes to see a doctor. The
population standard deviation is known to be 9 minutes. Compute the
value of the appropriate test statistic to test this claim.
