A pharmaceutical company has recently introduced a new pain killer into the market. The pain killer is sold in boxes that include 24 pills. The sales of the pain killer in the last 16 weeks have been 11797, 6724, 15346, 12825, 15939, 9997, 13671, 21994, 17774, 14587, 11190, 18083, 25320, 15129, 17092, and 27652 boxes. a. Use Holt's method with smoothing constants a = 0.7 and ß = 0.1 and develop a sales forecast for the next 2 weeks. b. Adjust the method and find the best values for a and ß that result in the least MSE. c. Use the method in part (b) to develop point and 90-percent prediction interval forecasts for the next 2 weeks' sales.
