Part $10$

$$Therefore$,$ the forecast for year $6$ is

$$

$3780$ miles$($round your response to two decimal$$ places$).$

Part $11$

What MAD results from using this approach to$$ forecasting?The MAD for the forecast developed using a weighted$2-$year moving average with weights of $\mathrm{.}4$ and $\mathrm{.}6=$
