A magazine wants to classify airports based on traveller ratings. A rating scale of 0 to 10 is used.
Airports with a population mean of 7 or more will be designated as a superior airport. The maga-
zine surveys a sample of 60 passengers at each airport. The sample for Heathrow airport in London
gives you a mean of 7.25 and a standard deviation of 1.052.
(i) Does this example require a one- or two-tailed test?
(ii) Should Heathrow be designated as a superior airport based on a level of significance of a = 0.05?
