Problem Solving 2: In the following table represents data on laptops sales for 7 periods. Data on Laptops Sales period Sales of Laptops 1 670 2 750 3 620 4 520 5 410 6 500 7 590 8 None Questions: 1. Compute The forecasting of the periods 5,6, and 8 using the Simple Moving Average of order 1, 3, and then 4. 2. Compute The forecasting of the periods 7, and 8 using the weighed moving average of order 2 (the weights are 15 and 5 from most recent period). 3. Compute The forecasting of the periods 6, and 8 using the weighed moving average of order 4 (the weights are 12, 6, 7, and 4 from most recent period). 4. Compute the forecasting of period 7, for demand of computers, using the exponential smoothing with a = 0.4 and F.= 500
