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 36 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?
