IS THE TRACKING SIGNAL WITHIN OR NOT WITH ACCEPTABLE LIMITS. WILL THUMBS UP RIGHT AWAY

Passenger miles flown on Northeast Airlines, a commuter firm serving the Boston hub, are shown for the past 12 weeks: 12 5 6 7 8 9 10 Week Actual Passenger Miles (in thousands) 1 17 2 21 3 19 4 23 11 15 18 16 20 18 22 20 22 a) Assuming an initial forecast for week 1 of 17,000 miles, use exponential smoothing to compute miles for weeks 2 through 12. Use a = 0.2 (round your responses to two decimal places). 1 2 3 4 5 6 8 9 10 11 12 Week Forecasted Passenger Miles (in thousands) 17.00 17.00 17.80 18.04 19.03 18.83 18.26 18.61 18.49 19.19 19.35 18.48 b) The MAD for this model = 2.38 (round your response to two decimal places). c) Compute the cumulative forecast errors, cumulative MAD, and tracking signals (round your responses to two decimal places).

The tracking signal is within acceptable limits. Enter your answer in each of the answer boxes. is not within is within
