The managing director of a consulting group has the accompanying monthly data on total overhead costs and professional labor hours to bill to clients. Complete parts a through c. Click the icon to view the monthly data. a. Develop a simple linear regression model between billable hours and overhead costs. Overhead Costs=151609.524 + 45.086 x Billable Hours (Round the constant to one decimal place as needed. Round the coefficient to four decimal places as needed. Do not include the $ symbol in your answers.) b. Interpret the coefficients of your regression model. Specifically, what does the fixed component of the model mean to the consulting firm? Interpret the fixed term, bo, if appropriate. Choose the correct answer below. 26 BE OA. For each increase of 1 unit in overhead costs, the predicted billable hours are estimated to increase by bo- B. The value of bo is the predicted billable hours for an overhead cost of 0 dollars. C.

G_2 D. For each increase of 1 unit in billable hours, the predicted overhead costs are estimated to increase by bo-
