Use $3-$period moving average and exponential smoothing techniques to forecast demand for period $17.$ For exponential smoothing technique use $($Alfo$)=0\mathrm{.}7$ and $($alfo$)=0\mathrm{.}4(2$ Points$).$

Finally, see which forecast is more accurate by using Mean absolute deviation $($MAO$)$ or MAPE techniques $(1$ Points$).$
