A pharmacist has been monitoring sales of a certain over-the-counter pain reliever. Daily sales during the last 15 days were Day:123456789 Number sold:323538374443414442 Day:101112131415 Number sold:484353445049 a. Assume the data refer to demand rather than sales. Using trend-adjusted exponential smoothing with an initial forecast of 48 for Day 8, an initial trend estimate of 2, and α = β = .2, 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.)
