Chapter 6.A, Problem 6P
Least-Square. Regression; Scattergraph; Comparison of Activity Bases
The Hard Rock Mining Company is developing cost formulas for management planning and decision-making purposes. The company’s cost analyst has concluded that utilities cost is a mixed cost, and he is attempting to find a base that correlates with the cost. The controller has suggested that tons mined might be a good base to use in developing a cost formula .The production superintendent disagrees, she thinks that direct labor-hours would be a better base. The cost analyst has decided to try both bases and has assembled the following information:
Required:
1. Using torn mined as the independent variable, prepare a scattergraph that plots tons mined on the horizontal axis and utilities cost on the vertical axis Using the least-squares regression method, estimate the variable utilities cost per ton mined and the total fixed utilities cost per quarter. Express these estimates in the form Y = a + bX.
2. Using direct labor-hours as the independent variable, prepare a scattergraph that plots direct labor-hours on the horizontal axis and utilities cost on the vertical axis. Using the least-squares regression method, estimate the variable utilities cost per direct labor-hour and the total fixed utilities cost per quarter. Express these estimates in the form Y = a+ bX.
3. Would you recommend that the company use tons mined or direct labor-hours as a base for planning utilities cost?

The additional data obtained through traditional allocation are not worth the cost. C. They want to improve the data on which decisions are made. D. A company only has one cost driver.arrow_forwardBecause of high production-changeover time and costs, a director of manufacturing must convince management that a proposed manufacturing method reduces costs before the new method can be implemented. The current production method operates with a mean cost of $220 per hour. A research study will measure the cost of the new method over a sample production period. Develop the null and alternative hypotheses most appropriate for this study. Comment on the conclusion when H0 cannot be rejected.
