Chapter 10, Problem 10.42P
Regression; choosing among models. Apollo Hospital specializes in outpatient surgeries for relatively minor procedures. Apollo is a nonprofit institution and places great emphasis on controlling costs in order to provide services to the community in an efficient manner.
Apollo’s CFO, Julie Chen, has been concerned of late about the hospital’s consumption of medical supplies. To better understand the behavior of this cost, Julie consults with Rhett Bratt, the person responsible for Apollo’s cost system. After some discussion, Julie and Rhett conclude that there are two potential cost drivers for the hospital’s medical supplies costs. The first driver is the total number of procedures performed. The second is the number of patient-hours generated by Apollo. Julie and Rhett view the latter as a potentially better cost driver because the hospital does perform a variety of procedures, some more complex than others.
Rhett provides the following data relating to the past year to Julie.
- 1. Estimate the regression equation for (a) medical supplies costs and number of procedures and (b) medical supplies costs and number of patient-hours. You should obtain the following results:
Required
Regression 1: Medical supplies costs = a + (b × Number of procedures)
Regression 2: Medical supplies costs = a + (b × Number of patient-hours)
- 2. On different graphs plot the data and the regression lines for each of the following cost functions:
- a. Medical supplies costs = a + (b × Number of procedures)
- b. Medical supplies costs = a + (b × Number of patient-hours)
- 3. Evaluate the regression models for “Number of procedures” and “Number of patient-hours” as the cost driver according to the format of Figure 10-18 (page 406).
- 4. Based on your analysis, which cost driver should Julie Chen adopt for Apollo Hospital? Explain your answer.

Louis Clark, the new administrator for the surgical clinic, was trying to figure out how to allocate is indirect expenses. His staff were complaining that the current method of taking a percentage of revenues was unfair. He decided to try to allocate utilities expense based on square footage of each department, to allocate administration expense based on direct costs, and to allocate laboratory expense based on tests. Using the information in Exhibit 12.11 below, calculate the total indirect costs (utilities, administration, and laboratory) allocated to the Day-Op Suite; Cystoscopy; and Endoscopy.

Harold Monette vacationed at Lake Tahoe last winter. Unfortunately, he broke his ankle while skiing and spent two days at the Sierra University Hospital. Monette’s insurance company received a $4,950 bill for his two-day stay. One item that caught Monette’s attention was a $10.60 charge for a roll of cotton. Monette is a salesman for Johnson & Johnson and knows that the cost to the hospital of the roll of cotton is between $2.45 and $3.25. He asked for a breakdown of the $10.60 charge. The accounting office of the hospital sent him the following information: Monette believes the overhead charge is outrageous. He comments, “There was nothing I could do about it. When they come in and dab your stitches, it’s not as if you can say, ‘Keep your cotton roll. I brought my own.’”arrow_forwardCould you outline the difference between a fixed cost and a variable cost?Could you identify which expense is a fixed cost and which is a variable cost from the information in the scenario (storage unit vs. hospital gowns)?Develop a plan to reduce both costs within the next fiscal year.arrow_forward
