Part $2$ of $5$

The Carbondale Hospital is considering the purchase of a new ambulance. The decision will rest partly on the anticipated mileage to be driven next year. The miles driven during the past $5$ yea as follows:

$\backslash$table$[[$Year$,1,2,3,4,5],[$Mileage$,3,000,4,050,3,400,3,850,3,700]]$

a$)$ Using a $2-$year moving average, the forecast for year $6=3775$ miles $($round your response to the nearest whole number$).$

b$)$ If a $2-$year moving average is used to make the forecast, the MAD based on this $=$ miles $($round your response to one decimal place$).($Hint: You will have only $3$ years of matched data.
