Question
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, X3 = safety patrol visibility, and X4 = friendliness of guest services.
