as follows:

$\backslash$table$[[$Year$,1,2,3,4,5],[$Mileage$,3,000,3,950,3,400,3,850,3,800]]$

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

d$)$ Using exponential smoothing with $=0\mathrm{.}40$ and the forecast for year $1$ being $3,000,$ the forecast for year $6=3664$ miles $($round your response to the nearest whole number$).$

My answers are:

part a: $3825$

Part b: $141\mathrm{.}67$

Part c$1$:$3817\mathrm{.}5$

Partc$2$:$194\mathrm{.}17$
