QUESTION 3-A Sales of industrial vacuum cleaners at R. Lowenthal Supply Co. over the past 13 months are as follows: SALES($1,000s) MONTH August September TITE SALES($1000s) MONTH January February 11 14 14 17 16 March 12 October 10 April 14 November 15 Мay 16 December 17 June 11 January jo back to bn 11 July eing m (a) Using a moving average with three periods, determine the demand for vacuum cleaners for next February. (b) Using a weighted moving average with three periods, determine the demand for vacuum cleaners for February. Use 3, 2, and 1 for the weights of the most recent, second most recent, and third most recent periods, respectively. For example, if you were forecasting the demand for February, November would have a weight of 1, December would have a weight of 2, and January would have a weight of 3. (c) Use exponential smoothing with a constant of 0.2 to forecast the demand for vacuum cleansers for January to February. (d) Evaluate the accuracy of each of these methods (Compute the MAD and MSE)) oback His
