When flights are delayed, do two of the worst airports experience delays of the same length? Suppose the delay times in minutes for seven recent, randomly selected delayed flights departing from each of these airports are as follows. Airport 1 Airport 2 69 107 95 37 44 33 31 88 53 76 27 41 45 58 H0: Median delay time for airport 1 − Median delay time for airport 2 ≤ 0 Ha: Median delay time for airport 1 − Median delay time for airport 2 > 0 Find the value of the test statistic.
