Chapter 11.1, Problem 4E

To determine

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

Answer to Problem 4E

The ordered stem-and-leaf plot is Ordered plot

  $\begin{array}{l}\text{1 1 2 6}\\ \text{2 }\\ \text{3 3 3 5 }\\ \text{4 2 4 7}\\ \text{5 0 3}\\ 6\text{ 0 7}\\ 7\text{ 2 7 9}\\ 8\\ 9\text{ 1 8}\end{array}$

Explanation of Solution

Given information: consider the data provided in the question.

  $\text{12,50,72,67,33,98,44,16,91,47,42,53,33,11,60,77,35,79}$ .

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

  $\begin{array}{l}\text{1 1 2 6}\\ \text{2 }\\ \text{3 3 3 5 }\\ \text{4 2 4 7}\\ \text{5 0 3}\\ 6\text{ 0 7}\\ 7\text{ 2 7 9}\\ 8\\ 9\text{ 1 8}\end{array}$

Hence,

Thus ,Ordered plot

  $\begin{array}{l}\text{1 1 2 6}\\ \text{2 }\\ \text{3 3 3 5 }\\ \text{4 2 4 7}\\ \text{5 0 3}\\ 6\text{ 0 7}\\ 7\text{ 2 7 9}\\ 8\\ 9\text{ 1 8}\end{array}$
