AAbout 25 percent
BAbout 60 percent
CAbout 40 percent
DAbout 75 percent
Answer & Solution
Correct answer: C. About 40 percent
1. A share is the count for the group divided by the total in the sample.
2. Here that is 305 divided by 755.
3. That comes to just over 0.40, which is about 40 percent.
4. The remaining 450 drivers, about 60 percent, do not use a cell phone while driving.
