A 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
Number sold:	36	38	42	44	48	49	50	49	52
Day:	10	11	12	13	14	15
Number sold:	48	53	55	55	56	55

Assume that the data refer to demand rather than sales. Using trend-adjusted smoothing with an initial forecast of 51 for week 8, an initial trend estimate of 3, and ? = ? = .2, develop forecasts for days 9 through 16. What is the MSE for the 8 forecasts for which there are actual data? (Round your intermediate calculations and final answer to 3 decimal places.)
