d. Do you ate? Why or why not? 9. Demand for a certain model of snowboard during the past 5 months is shown below. November 196 December 268 January 315 February March 299 101 a. Compute the forecast demand for each month from November through March, us- ing single exponential smoothing with a = 0.2. Assume that the forecast for No- vember was 212. b. Compute the MAD for this forecasting model based on the data for December, January, February, and March. d. Do you ate? Why or why not? 9.
