(c) Use a = 0.2 to compute the exponential smoothing values for the time series. Time Serles Value Week Forecast 1 19 2. 12 19 3 16 17.6 4 11 17.28 18 16.024 13 16.412 X Compute MSE. (Round your answer to two decimal places.) MSE - 21.32 What is the forecast for week 7? (Round your answer to two decimal places.) 15.74 (d) Compare the three-week moving average forecast with the exponential smoothing forecast using a - 0.2. Which appears to provide the better forecast based on MSE? Explain. O The exponential smoothing using a - 0.2 provides a better forecast since it has a larger MSE than the three-week moving average approach. O The three-week moving average provides a better forecast since it has a larger MSE than the smoothing approach using a - 0.2. O The exponential smoothing using a - 0.2 provides a better forecast since it has a smaller MSE than the three-week moving average approach. O The three-week moving average provides a better forecast since it has a smaller MSE than the smoothing approach using a = 0.2. (e) Use trial and error to find a value of the exponential smoothing coefficient a that results in a smaller MSE than what you calculated fora - 0.2.
