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 $5$ years are as follows:

a$)$ Using a $2-$year moving average, the forecast for year $6=3750$ 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 $=41\mathrm{.}7$ miles $($round your response to one decimal place$).($Hint: You will have only

$3$ years of matched data.$)$

c$)$ The forecast for year $6$ using a weighted $2-$year moving average with weights of $0\mathrm{.}35$ and $0\mathrm{.}65($the weight of $0\mathrm{.}65$ is for the most recent period$)=$ miles $($round

your response to the nearest whole number$).*$ Please show Work for B$)$ and C$)$
