B) The MAD for this model = ?

Passenger miles flown on Northeast Airlines, a commuter firm serving the Boston hub, are shown for the past 12 weeks: 1 2 3 4 5 6 7 8 9 10 11 12 Week Actual Passenger Miles (in thousands) 18 21 19 22 19 18 20 19 22 20 15 25 a) Assuming an initial forecast for week 1 of 18,000 miles, use exponential smoothing to compute miles for weeks 2 through 12. Use a = 0.25 (round your responses to two decimal places). 1 2 3 4 5 6 7 8 9 10 11 12 Week Forecasted Passenger Miles (in thousands) 18.00 18.00 18.75 18.81 19.61 19.46 19.10 19.33 19.25 19.94
