I need to see this problem solved out on paper in long form to understand the operations.

Question 1: The SC03001 Company is considering different tools to forecast the demand of its textbooks. Based on the following data for weekly sales to answer the questions. 3 4 6 a. 0.15, 14 - Week 1 2 5 Demand 35 47 46 32 26 33 Forecast the demand for Weeks 6 and 7 using a 3-week simple moving average (SMA) method. b. Forecast the demand for Weeks 6 and 7 using a 4-week weighted moving average (WMA) method with w1 = 0.5, W2 = 0.25, w3 0.1. Forecast the demand for Week 3 using exponential smoothing with Ao 33, compare the results from a = 0.3 and a = 0.2, respectively. Next, evaluate which a value gives a more accurate demand forecast for the first three weeks if we measure forecast error by (i) CFE (ii) regular MAD (iii) the smoothed MAD (with MAD. = 1) C. =
