Using the table above, calculate two forecasts using the following method:$-$

i$.$ First, for periods $4$ through $10,$ develop the exponentially smoothed

forecasts using a forecast for period $3(F_3)$ of $45\mathrm{.}0$ and an alpha of $0\mathrm{.}4.|$

ii$.$ Calculate the weighted moving average for periods $4$ through $10,$ using weights

of

$\mathrm{.}70,\mathrm{.}20,$ and $\mathrm{.}10,$ with $0\mathrm{.}70$ applied to the most recent data.

iii. Calculate the mean absolute deviation $($MAD$)$ for each forecasting

procedure. Which forecasting procedure would you select? Why?
