b. Develop a three-week moving average for this time series. Compute MSE and a forecast for week 7. Round your answers to two decimal places. Time Series Value 18 13 16 Week 1 2 3 4 5 6 MSE: The forecast for week 7: Week c. Use α = 0.2 to compute the exponential smoothing values for the time series. Compute MSE and forecast for week 7. Round your answers to two decimal places. Time Series Value 18 13 1 2 3 4 12 18 15 5 6 MSE: 16 12 Forecast 18 15 Forecast The forecast for week 7: 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? Three-week moving average
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 for a = 0.2. Find a value of a for the smallest MSE. Round your answer to three decimal places. α =
