b) The MAD for this model = thousand (round your respanse to two docimal places). c) Compute the Cumulative Forecast Errors, cumulative MAD in thousands, and tracking signals (round your rosponses to two decimal ploces). a) Assuming an inital forecast for week 1 of 18,000 miles, use exponential smoothing to compute miles for weeks 2 through 12 . Use =0.18 (roun two decimal places). b) The MAD for this model = thousand (round your response to two docimal places). c) Compute the Cumulative Forecast Errors, cumulative MAD in thousands, and tracking signals (round your responses fo two decimal places)
