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 Forecast 1 13 17 16 16 11 11 16 Period Actual 1 13.00 2 16.00 3 16.00 4 11.00 5 11.00 6 16.00 MAD: MSE: Exponential smoothing using a Exponential smoothing using a = 2 3 4 5 a=0.2 17.00 yields lower MAD. yields lower MSE. Forecast a=0.5 17.00
