A pharmacist has been monitoring sales of a certain over-the-counter pain reliever. Daily sales during the last 15 days were: Day: Number sold: Day: Number sold: 37 1305 40 2478 11 53 3325 4835 13 6655 5648 7 8 9 49 50 46 46 55 14 15 50 57 60 50 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.)
