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 $0\mathrm{.}4.[3$ marks$]$

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. $[3$ marks$]$ iii. Calculate the mean absolute deviation $($MAD$)$ for each forecasting procedure.
