The following table shows the actual demand observed over the last 11 years: Year Demand 1 2 3 4 5 6 7 8 9 10 11 7 8 6 7 13 8 13 13 10 9 8 This exercise contains only parts b, c, and d. b) Using the 3-year moving average, provide the forecast from periods 4 through 12 (round your responses to one decimal place). Year 4 5 6 7 8 9 10 11 12 Forecast c) Using the 3-year weighted moving average with weights 0.10, 0.30, and 0.60, using 0.60 for the most recent period, provide the forecast from periods 4 through 12 (round your responses to two decimal places). Year 4 5 6 7 8 9 10 11 12 Forecast d) Mean absolute deviation for the forecast developed using the 3-year moving average is 2.39 and for the 3-year weighted moving average is 2.56. Based on this information, the better forecast is achieved using the approach.
