(c) Use a = 0.2 to compute the exponential smoothing forecasts for the time series. Time Series Value Week 1 2 3 4 5 6 Week 1 2 3 17 4 11 5 15 9 10 6 16 13 Compute MSE. (Round your answer to two decimal places.) MSE = 14.79 ✓ What is the forecast for week 7? (Round your answer to two decimal places.) 14.45 (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. 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 = 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 smaller MSE than the smoothing approach. 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. (e) Use a smoothing constant of a = 0.4 to compute the exponential smoothing forecasts. Time Series Value 17 11 17 15 15.8 10 16 Forecast 15.64 13 14.51 14.81 x x [ | Forecast
