Passenger miles flown on Northeast Airlines, a commuter firm serving the Boston hub, are shown for the past 12 weeks: Week 4 Actual Passenger Miles (in thousands) 10 11 12 15 20 16 21 17 16 18 17 22 18 12 19 a) Assuming an initial forecast for week 1 of 15,000 miles, use exponential smoothing to compute miles for weeks 2 through 12. Use a= 0.22 (round your responses to two decimal places). Week 4 7 10 11 12 Forecasted Passenger 15.00 15.00 16.10 16.08 17.16 17.12 16.87 17.12 17.09 18.17 Miles (in thousands) b) The MAD for this model = thousand (round your response two decimal places). c) Compute the Cumulative Forecast Errors, cumulative MAD in thousands, and tracking signals (round your responses to two decimal places).
