Quizplus · Accepted Answer

To find the mean population, we need to add up all the populations and divide by the total number of counties.

\begin{align*}
	ext{Total Population} &= 28 + 22 + 11 + 16 + 26 + 21 \
&= 124 \
	ext{Mean Population} &= \frac{	ext{Total Population}}{	ext{Number of Counties}} \
&= \frac{124}{6} \
&= 20.7 	ext{ thousand}
\end{align*}

Therefore, the best choice is B because it correctly calculates the mean population.
