Determine whether the High-Low method or Regression Analysis is
better to predict monthly overhead costs. Explain which model is
the better? Why or why not?
Use absolute cell address in y = a + bX
formula (Use absolute August X Value) to predict January and
December overhead costs. Do you think these predicted overhead
costs are reasonable?
