Stem-and-Leaf Graphs (Stemplots), Line Graphs, and Bar Graphs · Exercise 10

David County has six high schools. Each school sent students to participate in a county-wide science competition. shows the percentage breakdown of competitors from each school, and the percentage of the entire student population of the county that goes to each school. Construct a bar graph that shows the population percentage of competitors from each school.

\begin{array}{|c|c|c|}\hline \text{High School} & \text{Science competition population} & \text{Overall student population} \\ \hline \text{Alabaster} & \text{28.9%} & \text{8.6%} \\ \hline \text{Concordia} & \text{7.6%} & \text{23.2%} \\ \hline \text{Genoa} & \text{12.1%} & \text{15.0%} \\ \hline \text{Mocksville} & \text{18.5%} & \text{14.3%} \\ \hline \text{Tynneson} & \text{24.2%} & \text{10.1%} \\ \hline \text{West End} & \text{8.7%} & \text{28.8%} \\ \hline\end{array}
