Textbook Question
Chapter 12.2, Problem 11E
Airline Ticket Purchases for Domestic and International Flights. A Bloomberg Businessweek subscriber study asked, “In the past 12 months, when traveling for business, what type of airline ticket did you purchase most often?” A second question asked if the type of airline ticket purchased most often was for domestic or international travel. Sample data obtained are shown in the following table.
Type of Flight | ||
Type of Ticket | Domestic | International |
First class | 29 | 22 |
Business class | 95 | 121 |
Economy class | 518 | 135 |
- a. Using a .05 level of significance, is the type of ticket purchased independent of the type of flight? What is your conclusion?
- b. Discuss any dependence that exists between the type of ticket and type of flight.
