Consider the following demand data:

Period $1$: $400$

Period $2$: $450$

Period $3$: $480$

Period $4$: $505$

Given this data, which of the following statements will be true?

$($please note that you do NOT need to do any calculations to answer this question$)$ Consider the following demand data:

Given this data, which of the following statements will be true?

$($please note that you do NOT need to do any calculations to answer this question$)$

Using the simple average forecasting technique will result in a positively biased forecast for period $4.$

Using the exponential smoothing forecasting technique $($with alpha$=0\mathrm{.}1)$ will result in unbiased forecasts $($i$.$e$.,$ ME$=0).$

Using the last period demand forecasting technique will result in systematic underpredictions of demand.

Using a two$-$period moving average forecasting technique will produce forecasts that are, on average, greater than actual demand.

None of the above.
