A teacher asked each of his students how many books were read during the summer. Which histogram accurately displays this data?

<h2>Answer:</h2>
The histogram that accurately displays this data is:
Histogram A
<h2>Step-by-step explanation:</h2>For a histogram we first divide the data into disjoint class intervals such that the width of the intervals is equal.
Here we divide the class interval as:
0-9 , 10-19 , 20-29 , 30-39 and 40-49
Also, on making a frequency table we may get the height of bars in the histogram corresponding to each class interval.
Class-Interval Frequency
0-9 9
10-19 6
20-29 3
30-39 3
40-49 3
This means that the height of the class interval 0-9 must be 9
10-19 must be 6
20-29 must be 3
30-39 must be 3
and 40-49 must be 3.
