Using these data:

$\backslash$table$[[,$Last Year,This Year$],[$January$,300,275],[$February$,400,375],[$March$,425,350],[$April$,450,425],[$May$,400,400],[$June$,460,350],[$July$,400,350],[$August$,300,275],[$September$,375,350],[$October$,500,],[$November$,550,],[$December$,500,]]$

Develop a forecast for the fourth quarter using:

a three$-$quarter, weighted moving average. Weight the most recent quarter $\mathrm{.}5,$ the second most recent $\mathrm{.}25,$ and the third $25.$

An exponential smoothing forecast with an alpha of $\mathrm{.}25$

NOTE: Do the problem using quarters, as opposed to forecasting separate months.
