a$)$ Assuming an initial forecast for week $1$ of $17,000$ miles, use exponential smoothing to compute miles for weeks $2$ through $12$ Use $\backslash$alpha $=025($round your responses to two decimal places$).$ b$)$ The MAD for this model $=$ thousand $($round your response to two decimal places$)$Are the tracking signals within acceptable limits$?$ The control limits for the tracking signal are set at $\backslash$pm $3$ MADs. The tracking signals acceptable limits$.$
