Question: Flight Operations The table below lists the times min required
Flight Operations The table below lists the times (min) required for randomly selected flights to taxi out for takeoff and the corresponding times (min) required to taxi in after landing. (See Data Set 15 in Appendix B.) All flights are Flight 1 of American Airlines from New York (JFK) to Los Angeles (LAX). Construct a 90% confidence interval estimate of the difference between taxi-out times and taxi-in times. What does the confidence interval suggest about the claim of the flight operations manager that for flight delays, more of the blame is attributable to taxi-out times at JFK than taxi-in times at LAX?
Assume that the paired sample data are simple random samples and that the differences have a distribution that is approximately normal.
