The first$$ forecast, Upper F $1,$ was derived by observing Upper A $1$ and setting Upper F $1$ equal to Upper A $1.$ Subsequent forecasts were derived by exponential smoothing.

Part $2$

The smoothing constant $($alpha$)$ used to derive the subsequent forecasts$=$

$$

$.20($round your response to two decimal $$places$).($Hint: To determine alpha$,$ use either the relationship for period $3$ or$4.)$

Part $3$

Using exponential$$ smoothing, the forecasted demand for period $5$ using the smoothing constant determined above$=$

$$
