Chapter 12.4, Problem 2P

To determine

To find: The box-and-whisker plot of given data set.

Answer to Problem 2P

  

Explanation of Solution

Given information:

A data set is given as − $\text{15 4 9 16 10 16 8 14 25 34}$ .

Calculation:

Given data set is, monthly sales of audio device(in million dollars): $\text{15 4 9 16 10 16 8 14 25 34}$ .

Arranging the data set from least to greatest −

  $\text{4 8 9 10 14 15 16 16 25 34}$

  $\begin{array}{l}\text{Minimum}=4\\ \text{Maximum}=34\\ \text{Median}\left(Q_2\right)=\frac{14+15}{2}=14.5\\ \text{First quartile}\left(Q_1\right)=9\\ \text{Third quartile}\left(Q_3\right)=16\end{array}$

Plotting box-and-whisker plot as below −
