Consider the time series below. Complete parts a through e below.

a$)$ Forecast the demand for Period $8$ using a two$-$period simple moving average.

The forecasted demand for Period $8$ using a two$-$period simple moving average is

$($Type an integer or a decimal. Do not round.$)$

b$)$ Calculate the MAD for the forecast in part a$.$

MAD $=$

$($Round to three decimal places as needed.$)$

c$)$ Forecast the demand for Period $8$ using a three$-$period simple moving average.

The forecasted demand for Period $8$ using a three$-$period simple moving average is

$($Round to two decimal places as needed.$)$

d$)$ Calculate the MAD for the forecast in part c$.$

MAD $=$

$($Round to three decimal places as needed.$)$

e$)$ Which forecast would you choose?

Choose the correct answer below.

A$.$ Choose the three$-$period simple moving average, because it has the higher MAD.

B$.$ Choose the three$-$period simple moving average, because it has the lower MAD.

C$.$ Choose the two$-$period simple moving average, because it has the lower MAD.

D$.$ Choose the two$-$period simple moving average, because it has the higher MAD.
