Using the Data Shown Below in Table 1, Compute the Mean

Using the data shown below in Table 1, compute the mean square error, mean absolute deviation, and mean absolute percentage error for the forecasts shown and then answer Questions
Table 1
$\begin{array}{|l|c|c|}\hline \text { Month } & \text { Forecast Demand } & \text { Actual Demand } \\\hline \text { April } & 170 & 180 \\\hline \text { May } & 225 & 200 \\\hline \text { June } & 210 & 200 \\\hline \text { July } & 260 & 240 \\\hline \text { August } & 200 & 230 \\\hline\end{array}$
-The mean absolute percentage error (MAPE) is:

A) less than or equal to 5%.
B) more than 5% but less than or equal to 10%.
C) more than 10% but less than or equal to 15%.
D) more than 15% but less than or equal to 20%.
