Textbook Question
Chapter 10, Problem 10.38P
Multiple regression (continuation of 10-42). After further discussion, Julie and Rhett wonder if they should view both the number of procedures and number of patient-hours as cost drivers in a multiple regression estimation in order to best understand Apollo’s medical supplies costs.
- 1. Conduct a multiple regression to estimate the regression equation for medical supplies costs using both number of procedures and number of patient-hours as independent variables. You should obtain the following result:
Required
Regression 3
Medical supplies costs = a + (b1 × No. of procedures) + (b2 × No. of patient-hours)
- 2. Evaluate the multiple regression output using the criteria of economic plausibility goodness of fit, significance of independent variables, and specification of estimation assumptions.
- 3. What potential issues could arise in multiple regression analysis that are not present in simple regression models? Is there evidence of such difficulties in the multiple regression presented in this problem? Explain.
- 4. Which of the regression models from Problems 10-42 and 10-43 would you recommend Julie Chen use? Explain.

- Linear cost approximation. Dr. Young, of Young and Associates, LLP, is examining how overhead costs behave as a function of monthly physician contact hours billed to patients. The historical data are as follows:arrow_forwardWeber Valley Regional Hospital has collected data on all of its activities for the past 16 months. Data for cardiac nursing care follow: Required: 1. Using the high-low method, calculate the variable rate per hour and the fixed cost for the nursing care activity. 2. Run a regression on the data, using hours of nursing care as the independent variable. Predict cost for the cardiac nursing care for September Year 2 if 1,400 hours of nursing care are forecast. Evaluate the regression equation. How comfortable are you with the predicted cost for September Year 2? 3. Upon looking into the events that happened at the end of Year 1, you find that the cardiology ward bought a cardiac-monitoring machine for the nursing station. Administrators also decided to add a new supervisory position for the evening shift. Monthly depreciation on the monitor and the salary of the new supervisor together total 10,000. Now, run two regression equations, one for the observations from Year 1 and the second using only the observations for the eight months in Year 2. Discuss your findings. What is your predicted cost of the cardiac nursing care activity for September Year 2?arrow_forwardLeast-Squares Regression Method; Scattergraph; Cost Behavior Professor John Morton has just been appointed chairperson of the Finance Department at Westland University.
