Chapter 7.5, Problem 16E

To determine

Select a suitable data display for the given data.

Answer to Problem 16E

The circle graph is suitable for this situation.

Explanation of Solution

Given:

The given data table is

Calculation:

The circle graph or pie chart is suitable for this situation, because it shows data as parts of a whole.

Find the angle for each section.

White $=\frac{25}{100}\times {360}^{°}={90}^{°}$

Red $=\frac{12}{100}\times {360}^{°}={43.2}^{°}$

Yellow $=\frac{1}{100}\times {360}^{°}={3.6}^{°}$

Black $=\frac{21}{100}\times {360}^{°}={75.6}^{°}$

Green $=\frac{3}{100}\times {360}^{°}={10.8}^{°}$

Silver $=\frac{27}{100}\times {360}^{°}={97.2}^{°}$

Blue $=\frac{6}{100}\times {360}^{°}={21.6}^{°}$

Brown $=\frac{5}{100}\times {360}^{°}={18}^{°}$

The circle graph is given below.
