Question

A trucking company considered a multiple regression model for relating the dependent variable of total daily travel time for one of its drivers (hours) to the predictors distance traveled (miles) and the number of deliveries of made. After taking a random sample, a multiple regression was performed and the equation is (time) = 0.068*(distance) + 0.916*(deliveries) - 0.158. Suppose for a given driver's day, he is scheduled to drive 199 miles and make 8 stops. How long would you expect it to take him?

We do not know the observations in the data set, so we cannot answer that question.

Explanation / Answer

(time) = 0.068*(distance) + 0.916*(deliveries) - 0.158

we are given that distance =199

and deliveries =8

thus answer is (time) = 0.068*199 + 0.916*8- 0.158=20.702 option 3
