Exercise 14-36 Algo

The maintenance manager at a trucking company wants to build a regression model to forecast the time (in years) until the first engine overhaul based on four predictor variables: (1) annual miles driven (in 1,000s of miles), (2) average load weight (in tons), (3) average driving speed (in mph), and (4) oil change interval (in 1,000s of miles). Based on driver logs and onboard computers, data have been obtained for a sample of 25 trucks. A portion of the data is shown in the accompanying table.

Time	Miles	Load	Speed	Oil
7.9	43.1	19.0	45.0	16.0
0.8	98.1	27.0	44.0	30.0
?	?	?	?	?
6.3	61.6	24.0	57.0	19.0

Predicted Time = + Miles + Load + Speed + Oil
