Researchers at Purdue University and Wichita State University found that airlines are doing a better job of getting passengers to their destinations on time. AirTran Airways and Southwest Airlines were among the leaders in on-time arrivals, with both having 88% of their flights arriving on time. But for the 12% of flights that were delayed, the dataset named AirDelay contains this information. - View the infotmation (data that realtes to the question) in the screenshot attatched. A) Formulate the hypothesis that can be used to test for a difference between the population mean minutes late for delayed flights by these two airlines. B) Identify the appropriate t-test. Explain your selection. C)Conduct the test using an α = .05. D) Interpret your results in the context of this problem.
