Question

the teacher wants the story to take most students 15 minutes or less to read. based on the box plot, should the teacher choose a different story? most students finish the story in 15 minutes or less. the teacher choose a different story.

Explanation:

In a box - and - whisker plot, the box represents the middle 50% of the data. If the right - hand side of the box (the third quartile \(Q_3\)) is at 15 or less, then 75% of the data is 15 or less. Looking at the given box - plot, the box (which contains the middle 50% of the data) is such that most of the box (and a large portion of the data including the median and \(Q_3\)) is at 15 or less. So most students (more than 50%) finish the story in 15 minutes or less.

Answer:

Most students do finish the story in 15 minutes or less. The teacher does not need to choose a different story.
