pharmacist has been monitoring sales of a certain over-the-counter pain reliever. Daily sales during the last 15 days were Day: 1 2 3 4 5 6 7 8 9 37 40 43 47 48 49 49 55 Number sold: Day: Number 10 11 12 13 14 15 54 55 53 52 61 58 sold: a. 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 = B = .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.) MSE 63 46
