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

The histogram is,

See the step by step solution

## Step 1. Given Information.

The provided stem-and-leaf plot is

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

## Step 2. Data Values.

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

$364,\text{}370,\text{}370,\text{}375,\text{}382,\text{}382,\text{}383,\text{}387,\text{}387,\text{}387,\text{}388,\text{}389,\text{}390,\text{}391,\text{}394,\text{}396,\text{}397$

## 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,
