(c) Use a smoothing constant of a = 0.6 to compute the exponential smoothing forecasts. (Round your answers to two decimal places.) Time Series Value Month t Forecast F, 1 105 135 3 120 105 5 90 6 120 7 145 8 140 9 100 10 80 11 100 12 110 Does a smoothing constant of 0.4 or 0.6 appear to provide more accurate forecasts based on MSE? O A smoothing constant of 0.6 is better than a smoothing constant of 0.4 since the MSE is less for 0.6 than for 0.4. O A smoothing constant of 0.4 is better than a smoothing constant of 0.6 since the MSE is greater for 0.4 than for 0.6. O A smoothing constant of 0.4 is better than a smoothing constant of 0.6 since the MSE is less for 0.4 than for 0.6. O A smoothing constant of 0.6 is better than a smoothing constant of 0.4 since the MSE is greater for 0.6 than for 0.4.
