Based on the given monthly sales data, it can be said that there is not a strong linear trend in sales over time. b) First, co-owner Bob Day wants to forecast by exponential smoothing by initially setting February's forecast equal to January's sales with a = 0.20. Using the forecasting method, Bob's forecast for the month of May is (round your response to two decimal places): Forecast Month Jan Feb Mar Apr May Sales 400 372 410 370 400.00 394.40 397.52 392.02 Second, co-owner Sherry Snyder wants to forecast using a three-period moving average. The forecast for the month of May is (round your response to two decimal places). Forecast Month Jan Feb Mar Sales 400 372 410 370 Apr May 394.00 384 c) Assume that May's actual sales figure turns out to be 410. For the forecast developed by Bob using exponential smoothing, the mean absolute deviation (MAD) decimal places) sales (round your response to two
