Friendly Bank is attempting to determine the cost behavior of its small business lending operations. One of the major activities is the application activity. Two possible activity drivers have been mentioned: application hours (number of hours to complete the application) and number of applications. The bank controller has accumulated the following data for the setup activity:

Required:
1. Estimate a regression equation with application hours as the activity driver and the only independent variable. If the bank forecasts 2,600 application hours for the next month, what will be the budgeted application cost?
2. Estimate a regression equation with number of applications as the activity driver and the only independent variable. If the bank forecasts 80 applications for the next month, what will be the budgeted application cost?
3. Which of the two regression equations do you think does a better job of predicting application costs? Explain.
4. Run a multiple regression to determine the cost equation using both activity drivers.
What are the budgeted application costs for 2,600 application hours and 80 applications?
