Final answer:
To sketch the region containing the lowest 17% and highest 17% of bone density scores, we can create a histogram or a box plot. The correct graph to choose in this case would be D, which represents a box plot with the lowest 17% and highest 17% values clearly indicated.
Step-by-step explanation:
In order to find the cutoff values separating the lowest 17% and highest 17% of bone density scores, we need to divide the scores into three categories:
- Lowest 17%
- Middle 66%
- Highest 17%
To sketch the region containing the lowest 17% and highest 17%, we can create a histogram or a box plot. The correct graph to choose in this case would be D, which represents a box plot with the lowest 17% and highest 17% values clearly indicated.
