A business travel magazine wants to classify transatlantic gateway airports according to the mean rating for the population of business travelers. A rating scale with a low score of 0 and a high score of 10 will be used, and airports with a population mean rating greater than 7 will be designated as superior service airport. The magazine staff surveyed a sample of 60 business travelers at each airport to obtain the rating data. The sample for London's Heathrow Airport provided a sample mean of x = 7.25 and a sample standard deviation of s = 1.052. With a level of significance of a=0.05, do the data indicate that Heathrow should be designated as a superior service airport? Develop a hypothesis test for which the decision to reject H0 will lead to the conclusion that the population mean rating for Heathrow Airport is greater than 7.

Calculate test statistic Using p-value to do the hypothesis test. Repeat the test using the critical value approach Do p-value approach and the critical value approach reach the same conclusion?
