b) The MAD for this model = thousand (round your response to two decimal places). c) Compute the Cumulative Forecast Errors, cumulative MAD in thousands, and tracking signals (round your responses to two decimal places). Are the tracking signals within acceptable limits? The control limits for the tracking signal are set at 4MADs.
