a) Assuming an initial forecast for week 1 of 15,000 miles, uso exponential sroothing to compute miles for weeks 2 through 12 . Use =0.25 (rour two docimal placess). b) The MAD for this model a thousand (round your rosponse to two decimal places). c) Compute the Cumulative Forecast Errors, cumulative MAD in thousands, and tracking signals (round your responses to two decimal places). b) The MAD for this model = thousand (round your responso fo two decimal places). c) Compule the Cumulative Forecast Errors, cumulative MAD in thousands, and tracking signals (round your responses fo two decimal places). Ave the tracking signals wunin acceptable limits? The control limits for the tracking signal afe set at \pm 3MADs. The tracking signals acceptable limits
