Flying Home for the Holidays Does the airline you choose affect when you'll arrive at your destination? 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. We are interested in testing whether the average difference between actual and scheduled arrival time is different between the two airlines.

Flying Home for the Holidays

Does the airline you choose affect when you'll arrive at your destination? The dataset DecemberFlights contains the difference between actual and scheduled arrival time from 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. We are interested in testing whether the average difference between actual and scheduled arrival time is different between the two airlines.

(b) Find the sample mean of each group, and calculate the difference in sample means. Round your answers to one decimal place. Mean for Delta = i Mean for United i Difference in means i (c) Use StatKey or other technology to create a randomization distribution and find the p-value. Round your answer to three decimal places. p-value
