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.

Question 1:We want to evaluate the impact on the monetary economy for a company of two types of strategy (competitive strategy, cooperative strategy) adopted by buyers.Competitive strategy: strategy characterized by firm behavior aimed at obtaining concessions from the buyer.Cooperative strategy: a strategy based on a problem-solving negotiating attitude, with a high level of trust and cooperation.A random sample of 17 buyers took part in a negotiation experiment in which 9 buyers adopted the competitive strategy, and the other 8 the cooperative strategy. The savings obtained for each group of buyers are presented in the pdf that i sent:
For this problem, we assume that the samples are random and come from two normal populations of unknown but equal variances.According to the theory, the average saving of buyers adopting a competitive strategy will be lower than that of buyers adopting a cooperative strategy.a) Specify the population identifications and the hypotheses H0 and H1…
