DS 13.6.3 contains an extension of the data set presented in DS 12.11.3 concerning the power loss that occurs in the bearing of an automobile engine. In addition to the diameter of the bearing, information is provided on the clearance and the length of the bearing.
What is the fitted model when the explanatory variables diameter and clearance are used? Calculate a 95% prediction interval for the power loss of an engine that has a bearing diameter of 25 and a bearing clearance of 0.07. Show that the largest standardized residual in absolute value is 2.46.
