Consider the following data that is listed in Exercise 12.15.

(a) Estimate ?2 using multiple regression of y on x1 and x2.

(b) Compute predicted values, a 95% confidence; inter value for mean wear, and a 95% prediction interval for observed wear if x1?= 2 and x2 = 1000.

* (oil viscosity) : (load) y (wear) 1.6 15.5 22.0 43.0 851

* (oil viscosity) : (load) y (wear) 1.6 15.5 22.0 43.0 851 816 1058 1201 1357 1115 193 230 172 91 113 125 33.0 40.0
