Question

teacher measures the heights, in inches, of some students in a classroom. The heights are shown on the histogram.



A histogram is shown. The horizontal axis shows the height in inches and the vertical axis shows the frequency. The horizontal axis is divided into six sections, and the vertical axis shows numbers from zero to eight. The top of the bar for heights from forty to forty-four is at six. The top of the bar for heights from forty-five to forty-nine is at seven. The top of the bar for heights from fifty to fifty-four is at three. There are no bars drawn for heights from fifty-five to sixty-four. The top of the bar for heights from sixty-five to sixty-nine is at one.

One student in the classroom is probably an adult.


Most of the students in the classroom are probably adults.


One student in the classroom is much shorter than the other students.


Most of the students in the classroom are around
55

Answer 1

Select only: "One student in the classroom is probably an adult."

Explanation: the histogram shows one student in the 65–69 in. bin (likely an adult). The other statements are not supported: most students are shorter (40–49 in.), only one is in the adult-height bin, there are zero in 55–64 in., and 7 out of 17 (not most) are in the 45–49 in. bin.
