Part (a) Use exponential smoothing to forecast this time series. Consider smoothing constants of a = 0.1 and 0.2. What is the forecast of the percentage of turnout in 1998?

Part (b) Use the mean absolute deviation (MAD) to determine which smoothing constant provides the best forecast of voter turnout. (Points : 30)
