(c) Use a 0.2 to compute the exponential smoothing Values for the time series. Week Time Series Value Forecast 1 19 2 2 12 19 3 14 176 4 10 16.88 5 16 15504 6 13 15,6032 Compute MSE. (Round your answer to two decimal places.) MSE3877 What is the forecast for week 77 (Round your answer to two decimal places) 15.00 (d) Compare the three-week moving average forecast with the exponential smoothing forecast using 0.2. Which appears to provide the better forecast based on MSE? Explain The three week moving average provides a better forecast since it has a smaller Me than the smoothing approach using a 0.2 The exponential smoothing using a 0.2 provides a better forecast since it has a matter 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 approach using 0,2 The exponential smoothing using a 0.2 provides a better forecast since it has a larger MSE than the three-week moving average approach X (e) Ute 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
