$4200\mathrm{.}4$

Group of answer choices

When the business environment is more dynamic, we tend to choose smaller smoothing constant value.

F$5=23\mathrm{.}33$ using Moving Average and n$=3$

F$5=23$ using Weighted Moving Average when n$=3$ and the weight is $0\mathrm{.}4,0\mathrm{.}3,$ and $0\mathrm{.}3$ for period $4,3,$ and $2$ with respectively.

F$5=20$ using Naive Approach
