The number of students who collected 3 or fewer bottles
The total number of students who collected 7 or fewer bottles

Answer 1

The number of students who collected exactly 2 bottles

Explanation:

Vertical axis is number of students and horizontal axis is number of bottles collected. Histograms represent data in bars, we can find the total number of students who collected bottles by reading the vertical axis. The number of students who collected bottles more than 4 and 8 can be viewed from the vertical axis because the ranges in horizontal axis are between 4-7 and 8-11.

The range on the horizontal axis is 0 to 3, we cannot tell how many students collected the exact number of bottles.

The correct option would be the number of students who collected exactly 2 bottles.
