3. 75%
Since the median value is 28, 50% of the students ran fewer than 28 laps. Additionally, the lower quartile is 13, which means that 25% of the students ran fewer than 13 laps. Therefore, a total of 50% + 25% = 75% of the students ran fewer than 28 laps.
Use the image 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?
