Suppose a four-period weighted average is being used to forecast demand. Weights for the periods are as follows: w4 = 0.1, w3 = 0.2, w2 = 0.3 and w1 = 0.4. Demand observed in the previous four periods was as follows: At-4 = 380, At-3 = 410, At-2 = 390, At-1 = 400. What will be the demand forecast for period t?
