Astudent was performed on a type of bearing to nd the relationship of amount of wear y to x1 = oil viscosity and x2 = load. The accompanying data were obtained. Complete parts (a) and (b) below. Click here to view the bearing data. Click here to view page 1 of the table of critical values of the t-distribution. Click here to view page 2 of the table of critical values of the tdistribution. (a) Estimate 02 using multiple regression of y on x1 and x2. 52 = 695.5 (Round to one decimal place as needed.) (b) Compute predicted values, a 95% condence intewal for mean wear, and a 95% prediction interval for observed wear if x1 = 15 and x2 = 1100. =D (Round to three decimal places as needed.) 0 Bearing Data
