Researchers at Purdue University and WichitaState University found that airlines are doing a better job of getting passengers totheir destinations on time (Associated Press, April 2, 2012). AirTran Airways andSouthwest Airlines were among the leaders in ontime arrivals with both having 88%of their flights arriving on time. But for the 12% of flights that were delayed, howmany minutes were these flights late? Sample data showing the number of minutesthat delayed flights were late are provided in the sheet named AirDelay. Data areshown for both airlines.(a) Formulate the hypotheses that can be used to test for a difference between thepopulation mean minutes late for delayed flights by these two airlines.(b) What is the sample mean number of minutes late for delayed flights for each ofthese two airlines?(c) Using a 0.05 level of significance, what is the p-value and what is your conclusion?
