Fall City Hospital has an outpatient clinic. Jeffrey Harper, the hospital’s chief administrator, is very concerned about cost control and has asked that performance reports be prepared that compare budgeted and actual amounts for medical assistants, clinic supplies, and lab tests. Past financial studies have shown that the cost of clinic supplies used is driven by the number of medical assistant labor hours worked, whereas lab tests are highly correlated with the number of patients served. The following information is...
