Assume the data refer to demand rather than sales. Using trend-adjusted exponential smoothing with an initial forecast of 46 for Day 8, an initial trend estimate of 2, and a = ß = .3, develop demand forecasts for Days 9 through 16. Then compute the resultant MSE using the error values from Days 8 through 15. (Round your intermediate period-by-period forecast and error values to 3 decimal places. Round your final MSE answer to 3 decimal places.) 9 51
