b.) the mad for this model=

c.) compute the cummulative forecast errors, cummulative MAD, and tracking signals (round your reponses to two decimal places)

Passenger miles flown on Northeast Airlines, a commuter firm serving the Boston hub, are shown for the past 12 weeks: Week 1 2 3 4 5 6 7 8 9 10 11 12 Actual Passenger Miles (in thousands) 16 21 17 22 19 18 2019 24 20 14 25 a) Assuming an initial forecast for week 1 of 16,000 miles, use exponential smoothing to compute miles for weeks 2 through 12. Use a 0.22 (round your responses to two decimal places). Week 1 2 3 4 5 6 7 8 9 10 11 12 Miles (in thousands) " 1600 16:00 1710 17.08 18.16 18.34 1827 18.65 18.73 19.89 0
