The manager of a driving school claims that the mean time taken to learn how to drive a car is 8 hours for all new drivers. A sample of 16 new drivers showed that the mean time taken by them to learn how to drive a car is 9.5 hours with a standard deviation of 1.5 hours. Test at the 1% significance level if the mean time taken to learn how to drive a car by all new drivers is greater than 8 hours.
