Question

7 the boxplot shows the number of videos rented by twenty people in one year. approximately what percent of people rented fewer than 60 videos? %

Explanation:

Step1: Recall the properties of a box - plot

In a box - plot, the left - most whisker represents the minimum value, the left end of the box is the first quartile ($Q_1$), the line inside the box is the median ($Q_2$), the right end of the box is the third quartile ($Q_3$), and the right - most whisker represents the maximum value. The first quartile ($Q_1$) represents the 25th percentile (25% of the data lies below $Q_1$), the median ($Q_2$) represents the 50th percentile (50% of the data lies below $Q_2$), and the third quartile ($Q_3$) represents the 75th percentile (75% of the data lies below $Q_3$).

Step2: Analyze the position of 60 on the box - plot

The value 60 is at the first quartile ($Q_1$) of the box - plot.

Answer:

25
