Chapter 11: Q. 18 (page 615)

Make a histogram from the stem-and-leaf plot. Don not use the same intervals in your histogram as are used in the stem-and-leaf plot.
$\begin{array}{l} \begin{matrix} 36 & 4 \\ 37 & 0 & 0 & 5 \\ 38 & 2 & 2 & 3 & 7 & 7 & 7 & 8 & 9 \\ 39 & 0 & 1 & 4 & 6 & 7 \end{matrix} \\ key: 36 | 4 = 364 \end{array}$

The histogram is,

Step by step solution

Step 1. Given Information.

The provided stem-and-leaf plot is

$\begin{array}{l} \begin{matrix} 36 & 4 \\ 37 & 0 & 0 & 5 \\ 38 & 2 & 2 & 3 & 7 & 7 & 7 & 8 & 9 \\ 39 & 0 & 1 & 4 & 6 & 7 \end{matrix} \\ key: 36 | 4 = 364 \end{array}$

Step 2. Data Values.

Write the data values by converting the stem-and-leaf plot.

$364, 370, 370, 375, 382, 382, 383, 387, 387, 387, 388, 389, 390, 391, 394, 396, 397$

Step 3. Frequency Table.

Make intervals of equal size for the provided data. For each interval, count the number of tally marks and write the frequency.

Intervals	Frequency
$360 - 370$	1
$370 - 380$	3
$380 - 390$	8
$390 - 400$	5

Step 4. Histogram.

Draw the horizontal and vertical axes. Label the intervals on the horizontal axis and the frequencies on the vertical axis.

Construct a bar to show the frequency of each interval.

Step 5. Conclusion.

The histogram is,
