Suppose a four period weighted average is being used to forecast demand. Weights for the periods are: Wt-4 = 0.05 Wt-3 = 0.15 Wt-2 = 0.35 Wt-1 = 0.45 Demand observed in the previous four periods was: At-4 = 10,907 At-3 = 9,976 At-2 = 9,733 At-1 = 9,673 What will be the demand forecast for period t? (Keep one decimal place in your answer)
