The McGraw Company is accumulating data to be used in preparing its annual profit plan
for the coming year. The cost behavior pattern of the maintenance costs must be
determined. The accounting staff has suggested that linear regression be employed to
derive an equation in the form of y = a + bx for maintenance costs. Data regarding the
maintenance hours and costs for last year and the results of the regression analysis are as
