A ski resort asked a random sample of guests to rate their satisfaction on various attributes of their visit on a scale of 1-5 with 1 = very unsatisfied and 5 = very satisfied. The estimated regression model was Y'= overall satisfaction score, X, = lift line wait, X, = amount of ski trail grooming. X} = safety patrol visibility, and X, = friendliness of guest services. Predictor Coefficient Intercept 2.9818 LiftWait e. 1642 Amount Groomed 0.2343 SkiPatrolVisibility 9. 0602 FriendlinessHosts -0. 1193 (a) Write the fitted regression equation. (Round your answers to 4 decimal places. Negative values should be Indicated by a minus sign.) y = *LiftWait + *AmountGroomed + *SkiPatrolVisibility + * FriendlinessHosts (b) Interpret each coefficient. Overall satisfaction |increases with an increase in satisfaction for each individual predictor except for friendliness of hosts. (c) Would the intercept seem to have meaning in this regression? O Yes O No (d) Make a prediction for Overall Satisfaction when a guest's satisfaction in all four areas is rated a 3. (Round your answer to 4 decimal places.) Overall satisfaction score
