Consider the following time series data.

. Use a=0.2 to compute the exponential smoothing values for the time series. Compute MSE and a forecast for week 7 . If required, round your MSE: The forecast for week 7: Compare the three-week moving average forecast with the exponential smoothing forecast using a=0.2. Which appears to provide the better 1 Explain. The input in the box below will not be graded, but may be reviewed and considered by your instructor. 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
