In Exercises 1-5, refer to the following list of departure delay times (min) of American Airline flights from JFK airport in New York to LAX airport in Los Angeles. Assume that the data are samples randomly selected from larger populations.

Comparing Two Means Treating the data as samples from larger populations, test the claim that there is a difference between the mean departure delay time for Flight 3 and Flight 21.
