Develop forecasts for June through October using the $3-$period moving average technique.

Develop forecasts for June through October using the simple exponential smoothing with an alpha of $0\mathrm{.}3.$ For the simple exponential smoothing model assume that the forecast for May is the actual demand for May.

Develop forecasts for June through October using the Holt's method $($trend$-$corrected exponential smoothing$).$ For Holt's model the regression equation has an intercept of $38\mathrm{.}0($F$\_$Jan$=38\mathrm{.}0)$ and a trend component of $3\mathrm{.}0($T$\_$Jan$=4\mathrm{.}0).$ Beta $=0\mathrm{.}3$ and alpha $=0\mathrm{.}3.$

Evaluate the three forecasts using the accuracy measure MAD for only June$-$September. Identify the forecasting method which is the most accurate and comment on the use of these three methods to generate a forecast in this situation.
