Answer
Explanation:
Step1: Recall box - plot properties
In a box - plot, the right - hand side of the box represents the third quartile ($Q_3$). The top 25 percent of the data lies above the third quartile.
Step2: Identify $Q_3$ from the box - plot
Looking at the box - plot, the value of the third quartile ($Q_3$) is 35. So the top 25 percent of the cars have a typical gas mileage of at least 35 miles per gallon.
