Provide an Appropriate Response If You Are Mostly Interested in the Number of People

Essay

Provide an appropriate response.
-Suppose that you want to construct a graph to represent the following data.
$$\begin{array} { l | c } \text { Blood Type } & \text { Frequency } \\\hline \mathrm { O } & 90 \\\mathrm {~A} & 84 \\\mathrm {~B} & 18 \\\mathrm { AB } & 8\end{array}$$
If you are mostly interested in the number of people in each category as a percentage of the total number of people, would a bar chart or a pie chart be more useful? Explain your thinking.
