Given the following data, use exponential smoothing with a = 0.2 and a = 0.5 to generate forecasts for periods 2 through 6. Use MAD and MSE to decide which of the two models produced a better forecast. (Round your answers to 2 decimal places, e.g.,2.25.) Period Actual 1 2 3 4 5 6 14.00 17.00 15.00 11.00 12.00 19.00 Period Actual Forecast 1 2 3 4 5 6 14 17 15 11 12 19 a = 0.2 18.00 18 Forecast a=0.5 18.00
