Problem $3-21($Algo$)$

Two different forecasting techniques $(F1$ and $F2)$ were used to forecast demand for cases of bottled water. Actual demand and the two sets of forecasts are as follows:

$\backslash$table$[[,,$PREDICTED DEMAND$],[$Period$,$Demand,F$1,$F$2],[1,68,62,67],[2,75,69,68],[3,70,72,70],[4,74,66,70],[5,69,73,72],[6,72,65,76],[7,80,74,79],[8,78,74,85]]$
