In a forecast by exponential smoothing, you start from an initial forecast, which is 8, and then receive a new observation, which is 12. Correspond- ingly, the next forecast is revised to 9. Question: (5 points) what is the value of a. A forecast is made by two independent exponential smoothing methods. Both methods start from the same initial forecast, which is 5. Then the first observed data is received and used to update the forecast for the second period by the two methods. One method uses a = 0.6 and the other uses a = 0.1. Question: (5 points) if both methods give the same forecast for the second period, what is the value of the observed data
