The weekly demand (in cases) for a particular brand of automatic dishwasher detergent for a chain of grocery stores located in Columbus, Ohio, follows. (b) Use a three-week moving average to develop a forecast (in cases) for week 11. (Round your answer to two decimal places.) F11= cases (c) Use exponential smoothing with a smoothing constant of =0.4 to develop a forecast (in cases) for week 11 . (Round your answer to two decimal places.) F11= cases (d) Which of the two methods do you prefer? Why? Exponential smoothing with =0.4 is preferable since it has a larger MSE compared to the 3 -week moving average. The 3-week moving average is preferable since it has a larger MSE compared to exponential smoothing with =0.4. The 3-week moving average is preferable since it has a smaller MSE compared to exponential smoothing with =0.4. Exponential smoothing with =0.4 is preferable since it has a smaller MSE compared to the 3 -week moving average
