Chapter PI, Problem 3RE

(a)

To determine

To explain how could that happen.

Explanation of Solution

In the question, the boxplot is shown that displays the heights in inches of $130$ members of choir. In the boxplot, there is parts of the choir in the horizontal axis and there is heights of the parts in the vertical axis. Thus, it appears that the median height for sopranos is missing, but actually the median and the upper quartile are equal. Therefore, this can happen if enough sopranos have a height of $65$ inches.

(b)

To determine

To write a few sentences describing what you see.

Explanation of Solution

In the question, the boxplot is shown that displays the heights in inches of $130$ members of choir. In the boxplot, there is parts of the choir in the horizontal axis and there is heights of the parts in the vertical axis. The distribution of height for each voice part is roughly symmetric. The basses are slightly taller than tenors. The sopranos and altos have about the same median height. Heights of basses and sopranos are more consistent than those of altos and tenors.
