b) For the forecast developed by BOB using exponential smoothing, the mean absolute value=__ sales

c) For the forecast developed by Sherry using a 3-Month moving average, the mean absolute value is= __sales

a) Based on the given monthly sales data, it can be said that there is linear trend in sales over time. b) First, co-owner Bob Day wants to forecast by exponential smoothing by initially setting Fobruary'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): 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)
