Compute MSE. (Round your answer to two decimal places.) MSE- What is the forecast for week 7? (Round your answer to two decimal places.) (d) Compare the three-week moving average approach with the exponential smoothing approach using a 0.2. Which appears to provide more accurate forecasts based on MSE? Explain. O The three-week moving average provides a better forecast since it has a smaller MSE than the smoothing approach. O The three-week moving average provides a better forecast since it has a larger MSE than the smoothing approach. O The exponential smoothing using a 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. 0.2 provides a better forecast since it has a smaller MSE than the three-week moving average approach. (e) Use a smoothing constant of a 0.4 to compute the exponential smoothing forecasts. Week Time Series Value 1 18 2 12 3 14 10 5 16 6 13 Forecast Does a smoothing constant of 0.2 or 0.4 appear to provide more accurate forecasts based on MSE? Explain. O The exponential smoothing using a -0.2 provides a better forecast since it has a larger MSE than the exponential smoothing using a = 0.4. O The exponential smoothing using a 0.4 provides a better forecast since it has a larger MSE than the exponential smoothing using a -0.2. O The exponential smoothing using a 0.2 provides a better forecast since it has a smaller MSE than the exponential smoothing using a 0.4. O The exponential smoothing using a -0.4 provides a better forecast since it has a smaller MSE than the exponential smoothing using a -0.2.
