Flying Hame far the Halidays, On Time The dataset December Flights contains the difference between actual and scheduled arrival time from 1000 randomly sampled December flights for twa of the major North American airlines, Delta Air Lines and United Air Lines. A negative difference indicates a flight arrived early Suppose that we are only interested in the proportion of flights arriving more than 30 minutes after the scheduled time. Of the 1000 Deita flights, 67 arrived mare than 30 minutes late, and of the 1000 United flights, 160 arrived mare than 30 minutes late We are testing to see if this provides evidence to conclude that the proportion of flights that are aver 30 minutes late is different between flying United or Delto. Let group 1 be Delta flights and group 2 be United flights. Click here for the dataset associated with this question.
