(d) Compare the three-week moving average forecast with the exponential smoothing forecast using a 02. Which appears to provide the better forecast based on MSE? - Select your answer - Explain. Using this approach results in a-Select your answer - MSE (e) Use trial and error to find a value of the exponential smoothing coefficient a that yields the minimum MSE. Do not round intermediate calculations. Use a two-decimal digit precision for the exponential smoothing coefficient. alpha
