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, X1 = lift line wait, X2 = amount of ski trail grooming, X3 = safety patrol visibility, and X4 = friendliness of guest services. Predictor Coefficient
Intercept 2.9233
LiftWait 0.1544
AmountGroomed 0.2403
SkiPatrolVisibility 0.0645
FriendlinessHosts −0.1291
(a) Write the fitted regression equation. (Round your answers to 4 decimal places. Negative values should be indicated by a minus sign.)
yˆy = + * LiftWait + * AmountGroomed + * SkiPatrolVisibility + * FriendlinessHosts
(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.)

The number of boys that left the camp doesn't actually matter. since 12 girls left the camp, 8 are left and now you have to find 3/4 of 8 which is 6. since 4 boys left camp you add that to 6 which means your answer is 10 tell me if you have any questions
