Given the following data, use exponential smoothing (z = 0.10) to develop a demand forecast. Assume the forecast for the initial period is 9. Period Demand 1 2 3 4 5 6 10 13 7 6 10 4 The exponential smoothing forecast is (round your responses to two decimal places): Period Forecast 1 2 9.00 9.10 3 4 5 9.40 8.80 8.70 6 7 9.10 8.50
