Using a 3-period moving average, forecast the sales for weeks 4 through 6. Use exponential smoothing with a = .3 to forecast sales for weeks 4 through 6. Use linear regression (time series) to develop a prediction equation that will forecast sales. Then use that prediction equation to get forecasts for weeks 4 through 6. Use MAD to pick the best forecasting method of A through C. d
