Which appears to provide the better forecast based on MSE? Explain. The exponential smoothing using a -0.2 provides a better forecast since it has a smaller MSE than the three week moving average approach The exponential smoothing using 0.2 provides a better forecast since it has a larger MSE than the three week moving average approach, The three week moving average provides a better forecast since it has a larger MSE than the smoothing approaching - 0.2 The three week moving average provides a better forecast since it has a smaller Me than the smoothing approach using a = 0.2 (e) Use trial and error to find a value of the exponential smoothing coefficient that results in a smaller MSE than what you calculated for 0.2 #02
