Chapter 11.1, Problem 9E

To determine

To calculate: to make an ordered stem-and-leaf plot of the data.

Answer to Problem 9E

The ordered stem-and-leaf plot is Ordered plot

  $\begin{array}{l}\\ \text{12 1 5 6}\\ \text{13 4 5 9}\\ \text{14 1 2}\\ \text{15 0 1 2 7 }\\ \text{16}\\ \text{17}\\ \text{18 0 }\end{array}$

Explanation of Solution

Given information: consider the data provided in the question.

  $13.5,15.7,15.0,12.6,14.2,15.1,18.0,13.9,15.2,14.1,12.5,12.1,13.4$ .

Calculation: to find the ordered stem-and-leaf plot of the data write the stem first. Then record each distance by writing its ones’ digit on the same line as its corresponding stem.

Ordered plot

  $\begin{array}{l}\\ \text{12 1 5 6}\\ \text{13 4 5 9}\\ \text{14 1 2}\\ \text{15 0 1 2 7 }\\ \text{16}\\ \text{17}\\ \text{18 0 }\end{array}$

Hence,

Thus ,Ordered plot

  $\begin{array}{l}\\ \text{12 1 5 6}\\ \text{13 4 5 9}\\ \text{14 1 2}\\ \text{15 0 1 2 7 }\\ \text{16}\\ \text{17}\\ \text{18 0 }\end{array}$
