Chapter 13, Problem 4PS

To determine

To graph: A stem and leaf plot of given histogram is to be drawn.

Explanation of Solution

Given information: A histogram is given as shown below:

  

Graph: Observations from given histogram:

In $0-9$ there are 3 numbers in the given data.

In $9-18$ there are 5 numbers in the given data.

In $18-27$ there are 4 numbers in the given data.

In $27-36$ there are 2 numbers in the given data

Now, on these observations we can make the stem-and-leaf plot by taking any randomly values.

In $0-9$ numbers are $3,5,7$

In $9-18$ numbers are $11,12,14,16,17$

In $18-27$ numbers are $22,24,25,26$

In $27-36$ numbers are $32,34$

Data: $3,5,7,11,12,14,16,17,22,24,25,26,32,34$

  

Interpretation:

Leaves represent the unit digits of the numbers and stem represent the tens digits.
