I COMM210 company is establishing an allocation rule for indirect costs. The average indirect cost from the past 12 weeks is $543.31. It plans to allocate total indirect costs to marketing and management accounting departments. The manager identified two potential allocation bases, a) direct labour hours billed and b) consulting fees generated by each department. The manager estimated two simple regressions of total indirect costs using direct labour hours and consulting fees as a predictor, respectively. The regression outputs and scatter graphs with regression lines are below. (a) Regression of indirect cost on dih (direct labour hours) a. b. Estimate Sid.

(a) Write down the estimated cost function from the regression output a. (b) Write down the estimated cost function from the regression output b. (c) Based on adjusted R2 of the two models, which cost driver is more appropriate for the allocation of indirect cost? (d) Based on the unit variable cost estimates of the two models, which cost driver is more appropriate for the allocation of indirect cost? (e) Based on the fixed cost estimates of the two models, which cost driver is more appropriate for the allocation of indirect cost? 0001 Indirect Cost 000L 00 0 Indirect Cost
