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 28 laps?

Answer choices.
A. 50%
B. 75%
C. 25%
D. 100%
To determine the percentage of 6th graders who ran fewer than 28 laps, we need to look at the lower quartile, which is 13, and divide it by the total range of laps (62-6=56).
So, the percentage of 6th graders who ran fewer than 28 laps is (28-6)/(62-6) = 22/56 = 0.393 or approximately 39.3%.
Therefore, the closest answer choice is:
A. 50%
