Flying Home for the Holidays, On Time The dataset DecemberFlights contains the difference between actual and scheduled arrival time from 1000 randomly sampled December flights for two 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 Delta flights, 67 arrived more than 30 minutes late, and of the 1000 United flights, 160 arrived more than 30 minutes late. We are testing to see if this provides evidence to conclude that the proportion of flights that are over 30 minutes late is different between flying United or Delta. Let group 1 be Delta flights and group 2 be United flights. Click here for the dataset associated with this question. Use the second edition. If using StatKey, the data needed is preloaded as Late Arrival-2e (Delta vs United, 2014).

The dataset DecemberFlights contains the difference between actual and scheduled arrival time from 1000 randomly sampled
December flights for two 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 Delta flights, 67 arrived more than 30 minutes late, and of the 1000 United flights, 160 arrived more than 30 minutes
late. We are testing to see if this provides evidence to conclude that the proportion of flights that are over 30 minutes late is different
between flying United or Delta.
Let group 1 be Delta flights and group 2 be United flights.
