Concept explainers
The Condé Nast Traveler Gold List provides ratings for the top 20 small cruise ships. The following data shown are the scores each ship received based upon the results from Condé Nast Traveler’s annual Readers’ Choice Survey. Each score represents the percentage of respondents who rated a ship as excellent or very good on several criteria, including Itineraries/Schedule, Shore Excursions, and Food/Dining. An overall score is also reported and used to rank the ships. The highest ranked ship, the Seabourn Odyssey, has an overall score of 94.4, the highest component of which is 97.8 for Food/Dining.
- a. Determine the estimated regression equation that can be used to predict the overall score given the scores for Itineraries/Schedule, Shore Excursions, and Food/Dining.
- b. Use the F test to determine the overall significance of the relationship. What is your conclusion at the .05 level of significance?
- c. Use the t test to determine the significance of each independent variable. What is your conclusion at the .05 level of significance?
- d. Remove any independent variable that is not significant from the estimated regression equation. What is your recommended estimated regression equation?
