Assume the data refer to demand rather than sales. Using trend-adjusted exponential smoothing with an
initial forecast of 44 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.)
