Consider the following time series data. Week 1 2 3 4 5 6 Value 19 14 16 11 17 15 Develop the three-week moving average forecasts for this time series. Compute MSE and a forecast for week 7 (to 2 decimals if necessary). MSE   The forecast for week    Use alpha=.2  to compute the exponential smoothing forecasts for the time series. Compute MSE and a forecast for week 7 (to 2 decimals). MSE   The forecast for week    Compare the three-week moving average approach with the exponential smoothing approach using alpha=.21 . Which appears to provide more accurate forecasts based on MSE?- Select your answer -The three-week moving average provides a better forecast since it has a smaller MSEThe exponential smoothing approach provides a better forecast since it has a smaller MSEThe three-week moving average provides a better forecast since it has a larger MSE
