Only need help with part e please!

Consider the following time series data. Week 1 2 3 4 5 6 Value 16 13 18 11 15 14 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 Week Value Forecast 1 16 2 13 3 18 4 11 15.67 5 15 14.00 6 14 14.67 MSE: 7.74 The forecast for week 7: 13.33 c. Use a = 0.2 to compute the exponential smoothing values for the time series. Compute MSE and a forecast for week 7. Round your answers to two decimal places. Time Series Week Value Forecast 1 16 2 13 16.00 3 18 15.40 4 11 15.92 5 15 14.94 6 14 14.95 MSE: 8.17 The forecast for week 7: 14.76 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. a = 0.400
