Use the details to answer the question.
A vertical number line labeled the Number of Laps Run ranges from 6 to 62 in increments of 2, with numbers marked in increments of 4. A box plot to the right of the number line shows the following: the minimum value is 6; the maximum value is 62; the lower quartile is 13; the median value is 28, and the upper quartile is 43.5.
The box plot represents the number of laps a group of 6th graders were able to run. Approximately what percentage of 6th graders ran fewer than 13 laps?

Answer Choices.
A. 50%
B. 12.5%
C. 75%
D. 25%
To find the percentage of 6th graders who ran fewer than 13 laps, we need to look at the lower quartile, which is 13. The lower quartile represents the 25th percentile. Since quartiles divide the data into four equal parts, approximately 25% of the 6th graders ran fewer than 13 laps.
Therefore, the answer is D. 25%.
