(a) using three-month moving average and (b) use exponential smoothing with a = 0.3, a = 0.6, and a = 0.9 to forecast the battery sales. Assume the forecast for Year 1 was 10 batteries based on the analysis in part (a) and (b), which method moving average or exponential smoothing with a = 0.3, a= 0.6, or a = 0. 9 provides the better forecast? Explain

Using exponential smoothing with a weight of a= 0.3, a= 0.6 and a weight of a = 0.9, develop Forecast for year 2 through 6. Compare the accuracy of the three forecasts including moving average using MAD and MSE.
