Explanation:

Step1: Identify median in box plot

The line inside the box of a box plot represents the median (50th percentile), which is marked at 7.5 hours here.

Step2: Interpret percentile meaning

The median divides the data: 50% of data is above the median, 50% is below. So parents who slept more than 7.5 hours make up 50% of the group.

Answer:

B. 50
