Chapter 10, Problem 10.28E
Estimating a cost function, high-low method. Lacy Dallas is examining customer-service costs in the southern region of Camilla Products. Camilla Products has more than 200 separate electrical products that are sold with a 6-month guarantee of full repair or replacement with a new product. When a product is returned by a customer a service report is prepared. This service report includes details of the problem and the time and cost of resolving the problem. Weekly data for the most recent 8-week period are as follows:
| Week | Customer-Service Department Costs | Number of Service Reports |
| 1 | $13,300 | 185 |
| 2 | 20,500 | 285 |
| 3 | 12,000 | 120 |
| 4 | 18,500 | 360 |
| 5 | 14,900 | 275 |
| 6 | 21,600 | 440 |
| 7 | 16,500 | 350 |
| 8 | 21,300 | 315 |

What variables, in addition to number of service reports, might be cost drivers of weekly customerservice costs of Camilla Products?
Use the high-low method to compute the cost function relating customer-service costs to the number of service reports.
Horton Manufacturing Incorporated produces blinds and other window treatments for residential homes and offices. The owner is
concerned about the maintenance costs for the production machinery because maintenance costs for the previous fiscal year were
higher than he expected. The owner has asked you to assist in estimating future maintenance costs to better predict the firm's
profitability. Together, you have determined that the best cost driver for maintenance costs is machine hours. The data from the
previous fiscal year for maintenance costs and machine hours follow:

- Barkoff Enterprises, which uses the high-low method to analyze cost behavior, has determined that machine hours best explain the company's utilities cost. The company's relevant range of activity varies from a low of 600 machine hours to a high of 1,100 machine hours, with the following data being available for the first six months of the year: Month Utilities Machine Hours January $8,700 800 February 8,360 720 March 8,950 810 April 9,360 920 May 9,625 950 June 9,150 900 The variable utilities cost per machine hour for Barkoff is: Select one: a. $5.00. b. $4.50. c. $0.18 d. $5.50.e.

Select the formula and enter the amounts to calculate the variable cost per inspection. (Round to the nearest cent.) Requirements 1. Use the high-low method to calculate the variable cost per inspection. 2. Calculate the total fixed costs. 3. Write the equation and calculate the operating costs for 800 inspections. 4. Draw a graph illustrating your total cost under this plan. Show the costs at 700, 800, and 1,200 inspections. (Use the high-low method for all calculations.)arrow_forwardJohnson Filtration. Inc., provides maintenance service for water filtration systems throughout southern Florida. Customers contact Johnson with requests for maintenance service on their water filtration systems. To estimate the service time and the service cost. Johnson’s managers want to predict the repair time necessary for each maintenance request. Hence, repair time in hours is the dependent variable. Repair time is believed to be related to three factors: the number of months since the last maintenance service, the type of repair problem (mechanical or electrical), and the repairperson who performs the repair (Donna Newton or Bob Jones). Data for a sample of 10 service calls are reported in the following table: Develop the simple linear regression equation to predict repair time given the number of months since the last maintenance service, and use the results to test the hypothesis that no relationship exists between repair time and the number of months since the last maintenance service at the 0.05 level of significance. What is the interpretation of this relationship? What does the coefficient of determination tell you about this model? Using the simple linear regression model developed in part (a), calculate the predicted repair time and residual for each of the 10 repairs in the data. Sort the data in ascending order by value of the residual. Do you see any pattern in the residuals for the two types of repair? Do you see any pattern in the residuals for the two repairpersons? Do these results suggest any potential modifications to your simple linear regression model? Now create a scatter chart with months since last service on the x-axis and repair time in hours on the y-axis for which the points representing electrical and mechanical repairs are shown in different shapes and/or colors. Create a similar scatter chart of months since last service and repair time in hours for which the points representing repairs by Bob Jones and Donna Newton are shown in different shapes and/or colors. Do these charts and the results of your residual analysis suggest the same potential modifications to your simple linear regression model? Create a new dummy variable that is equal to zero if the type of repair is mechanical and one if the type of repair is electrical. Develop the multiple regression equation to predict repair time, given the number of months since the last maintenance service and the type of repair. What are the interpretations of the estimated regression parameters? What does the coefficient of determination tell you about this model? Create a new dummy variable that is equal to zero if the repairperson is Bob Jones and one if the repairperson is Donna Newton. Develop the multiple regression equation to predict repair time, given the number of months since the last maintenance service and the repairperson. What are the interpretations of the estimated regression parameters? What does the coefficient of determination tell you about this model? Develop the multiple regression equation to predict repair time, given the number of months since the last maintenance service, the type of repair, and the repairperson. What are the interpretations of the estimated regression parameters? What does the coefficient of determination tell you about this model? Which of these models would you use? Why?arrow_forward
