2 histograms, the first titled Population in Niger and the second titled Population in Somalia. 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 6, with no bars from 7 to 10. The height of the bars descends from 2 to 6: bar 1 is the same height as bar 3. The bars in the second histogram are grouped on the high end, from 5 to 10, with no bars from 1 to 4. The height of the bars ascends from 5 to 9: bar 10 is the same height as bar 8.

5. Scientists measured the height of the giraffes in two different populations. Which population has the largest number of tall giraffes?
Responses

a
The population in Niger has the largest number of tall giraffes.
The population in Niger has the largest number of tall giraffes.

b
The population in Somalia has the largest number of tall giraffes.
The population in Somalia has the largest number of tall giraffes.

c
Both populations have the same number of tall giraffes.
Both populations have the same number of tall giraffes.

d
These bar graphs do not show which population has more tall giraffes.

Answer 1

Based on the description of the histograms:

• The first histogram (Population in Niger) shows giraffes mostly in the height range of 1 to 6, with no bars from 7 to 10, indicating no tall giraffes.
• The second histogram (Population in Somalia) has bars for height in the range of 5 to 10, with the tallest bars at heights 8, 9, and 10.

Since the population in Somalia has giraffes represented in the tall height ranges (5 to 10), and the population in Niger does not have any tall giraffes (7 to 10), the answer is:

b. The population in Somalia has the largest number of tall giraffes.
