Perform a statistical analysis/test of hypothesis, showing all the steps in hypothesis testing. 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 airports. The magazine staff surveyed a sample of 60 business travelers at each airport to obtain the ratings data. The sample for London’s Heathrow Airport provided a sample mean rating of 7.25 and a sample standard deviation of 1.052. Do the data indicate that Heathrow should be designated as a superior service airport?
