Question

Use the data to make a frequency table and a histogram.

$66,78,91,42,45,88,69,73,76,80,50,63,57,54,71,66$

Short answer

The frequency table and the histogram are as follows:

Intervals	Frequency
$40-60$	5
$60-80$	7
$80-100$	3

Step-by-step solution

Step 1. Given Information.

The provided numbers are,

$66,78,91,42,45,88,69,73,76,80,50,63,57,54,71,66$

Step 2. Frequency Table.

Make intervals of equal size for the provided data. Record the interval in which a particular data value lies by using the tally marks. For each interval, count the number of tally marks and write the frequency.

Intervals	Tally Marks	Frequency
$40-60$	$\cancel{\left|\right|\left|\right|}$	5
$60-80$	$\cancel{\left|\right|\left|\right||}\left|\right|$	7
$80-100$	$\left|\right||$	3

Step 3. 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 3. Conclusion.

The frequency table and the histogram are as follows:

Intervals	Frequency
$40-60$	5
$60-80$	7
$80-100$	3
