Chapter 11, Problem 2CT

To determine

To make: a stem-and-leaf plot and a histogram of the data.

Answer to Problem 2CT

Ordered plot

  $\begin{array}{l}\text{52 2 9}\\ \text{53 1 1 8 }\\ \text{54 0 2 8 }\\ \text{55 }\\ \text{56 2 4 6}\end{array}$

Explanation of Solution

Given information :

  $542,529,564,531,566,538,562,540,522,548,531$

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

  $\begin{array}{l}\text{52 2 9}\\ \text{53 1 1 8 }\\ \text{54 0 2 8 }\\ \text{55 }\\ \text{56 2 4 6}\end{array}$

Hence,

Ordered plot

  $\begin{array}{l}\text{52 2 9}\\ \text{53 1 1 8 }\\ \text{54 0 2 8 }\\ \text{55 }\\ \text{56 2 4 6}\end{array}$
