Sago Co. uses regression analysis to develop a model for predicting overhead costs. Two different cost drivers
(machine hours and direct materials weight) are under consideration as the independent variable. Relevant data were run on a computer using one of the standard regression programs, with the following results:
Coefficient Machine hours Y Intercept 2,500 B 5.0 R2= .70 Direct materials weight Y Intercept 4,600 B 2.6 R2= .50 What regression equation should be used?
a. Y = 2,500 + 5.0X
b. Y = 2,500 + 3.5X
c. Y = 4,600 + 2.6X
d. Y = 4,600 + 1.3X
