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, Note: To get full credit, you must answer All following questions, AND show your regression analysis results for questions (1) and (4). Questions: (1) Using Excel to conduct regression analysis (refer to instructions in Appendix 13.2 on page 635 in textbook 2) to 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 Answer: (2) Use the F test to determine the overall significance of the relationship. What is your conclusion at the 0.05 level of significance? Answer: (3) Use the t test to determine the significance of each independent variable. What is your conclusion at the 0.05 level of significance? Answer: (4) Remove any independent variable that is not significant from the estimated regression equation, and redo the regression analysis. What is your new estimated regression equation and what are your observations (open-ended question)?
