2 histograms, the first titled Giraffes in the Wild and the second titled Giraffes in the Nature Preserve. The Y-axis of each histogram is labeled Number of Giraffes, and the X-axis is labeled Height in intervals from 1 to 10, with 1 labeled Short and 10 labeled Tall. The bars in the first histogram are grouped on the low end, from 1 to 7, with no bars at 8, 9, and 10. The height of the bars descends from 1 to 7. The bars in the second histogram are grouped on the high end, ascending from 4 to 9, with no bars from 1 to 3. Bar 10 is the same height as bar 8.

17. Scientists measured the height of giraffes in two populations—one in the wild and one in a nature preserve. Which statement best describes the difference between the two populations?
Responses

a
There is more variation in height of the giraffes found in the wild.
There is more variation in height of the giraffes found in the wild.

b
There is more variation in height of the giraffes found in the nature preserve.
There is more variation in height of the giraffes found in the nature preserve.

c
The giraffes in the wild are mostly shorter than the giraffes found in the nature preserve.
The giraffes in the wild are mostly shorter than the giraffes found in the nature preserve.

d
The giraffes in the wild are mostly taller than the giraffes found in the nature preserve.

Answer 1

The best statement that describes the difference between the two populations of giraffes based on the information provided is:

c. The giraffes in the wild are mostly shorter than the giraffes found in the nature preserve.

This conclusion is drawn from the observation that the first histogram (Giraffes in the Wild) shows a significant concentration of giraffes at shorter heights (from 1 to 7), while the second histogram (Giraffes in the Nature Preserve) shows a concentration at taller heights (from 4 to 9), indicating that the giraffes in the wild tend to be shorter overall compared to those in the nature preserve.
