1. Using regression, determine the best cost formula to explain this company's monthly overhead costs. Explain how and why you reached this conclusion. Clearly write out the complete cost formula (round all amountsfrates to the nearest ce of}. A complete answer will thoroughly explain not only my this cost formula is valid. but also why this model's cost driver {or multiple cost drivers) isi'are better than any other combination of cost drivers available to predict monthly overhead costs. (For purposes of checking validity, all relevant regression assumptions should be named and adequately evaluated. Be sure to explain hDW you evaluated these assumptions.)
