Hi, i need help with this question.

Problem 3-17 pharmacist has been monitoring sales of a certain over-the-counter pain reliever, Daily tales during the last 15 days were 1 2 5 6 7 89 39 47 47 46 52 50 48 55 Day: Number soldi Day Number oldt 10 12 13 14 15 54 60 57 4. 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 B2, 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 5852
