Chapter 3, Problem 17E
Deepa Dalal opened a free-standing radiology clinic. She had anticipated that the costs for the radiological tests would be primarily fixed, but she found that costs increased with the number of tests performed. Costs for this service over the past nine months are as follows:
Required:
- 1. Prepare a scattergraph based on the preceding data. Use cost for the vertical axis and number of radiology tests for the horizontal axis. Based on an examination of the scattergraph, does there appear to be a linear relationship between the cost of radiology service and the number of tests?
- 2. Compute the cost formula for radiology services using the high-low method.
- 3. Calculate the predicted cost of radiology services for October for 3,500 tests using the formula found in Requirement 2.

David Jones, the new administrator for a surgical clinic, was trying to determine how to allocate his indirect expenses. His staff was complaining that the current method of taking a percentage of revenues was unfair. He decided to try to allocate utilities based on square footage of each department, administration based on direct costs, and laboratory based on tests. Use the information in the chart below to answer problems 22, 23 and 24.

Kara Meyer, owner of Flower Power, operates a local chain of floral shops. Each shop has its own delivery van. Instead of charging a flat delivery fee, Meyer wants to set the delivery fee based on the
distance driven to deliver the flowers. Meyer wants to separate the fixed and variable portions of her van operating costs so that she has a better idea how delivery distance affects these costs. She has the

As for other data, it remains unchanged. Question: Calculate the capacity cost rate per minute for each employee position in the hospital.

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.

Why?arrow_forwardGlencoe Medical Clinic operates a cardiology care unit and a maternity care unit. Colby Hepworth, the clinic’s administrator, is investigating the charges assigned to cardiology patients. Currently, all cardiology patients are charged the same rate per patient day for daily care services. Daily care services are broadly defined as occupancy, feeding, and nursing care. A recent study, however, revealed several interesting outcomes. First, the demands patients place on daily care services vary with the severity of the case being treated. Second, the occupancy activity is a combination of two activities: lodging and use of monitoring equipment. Since some patients require more monitoring than others, these activities should be separated. Third, the daily rate should reflect the difference in demands resulting from differences in patient type. Separating the occupancy activity into two separate activities also required the determination of the cost of each activity. Determining the costs…arrow_forward

Assume the hospital was able to make improvements such that the average length of stay in the hospital for the bypass was reduced from 6 days to 5 days. Further assume that additional improvements in medical technology reduced the operating room time for a bypass to 2½ hours. Determine the activity cost per patient for the coronary bypass treatment under these revised conditions. What is the cost improvement? The cost of treating a patient for a coronary bypass declined from $ to $, or $.arrow_forwardJohn Fleming, chief administrator for Valley View Hospital, is concerned about the costs for tests in the hospital's lab. Charges for lab tests are consistently higher at Valley View than other hospitals and have resulted in many complaints. Also, because of strict regulations on amounts reimbursed for lab tests, payments received from insurance companies and governmental units have not been high enough to cover lab costs. Mr. Fleming asked you to evaluate costs in the hospital's lab for the past month. The following information is available: a. Two types of tests are performed in the lab-blood tests and smears. During the past month, 1,250 blood tests and 3,900 smears were performed in the lab. b. Small glass plates are used in both types of tests. During the past month, the hospital purchased 19,500 plates at a cost of $73,320. 2,900 of these plates were unused at the end of the month; no plates were on hand at the beginning of the month. c.

Given her patient-load pressures, Dr. Gomez is excited to try out the new technique. By decreasing the time spent on eye treatments or procedures, she can increase her total revenues by performing more services within a work period. In order to implement the new procedure, special equipment costing $88,800 is needed. The equipment has an expected life of 4 years, with a salvage value of $7,200. Dr. Gomez estimates that her cash revenues will increase by the following amounts: Year Revenue Increases 1. $23,760 2. $32,400 3. 38,880 4. 38,880 Conceptual Connection: Compute the NPV for the project, using 14% as the IRR.arrow_forwardAlter's Home Center (AHC) sells renovation and remodeling products to both contractors and individual home owners.
