Question

last week, the bay city bus company tracked how long their school buses took to complete their routes. this box plot shows the results. length of route (min.) what percent of the buses completed their routes in 27 to 30 minutes? % submit

Explanation:

Step1: Recall the properties of a box - plot

In a box - plot, the box represents the inter - quartile range (IQR). The IQR contains 50% of the data. The left edge of the box is \(Q_1\) (first quartile) and the right edge is \(Q_3\) (third quartile).

Step2: Analyze the given box - plot

The interval from \(Q_1\) to \(Q_3\) in a box - plot corresponds to the middle 50% of the data. If we assume that the box in the given box - plot has \(Q_1 = 27\) and \(Q_3=30\) (by visual inspection of the scale on the number line for the box - plot).

Answer:

50
