Last year, Nicholas started babysitting to earn extra spending money. Over the summer, he

tracked how much money he earned at each babysitting job. This box plot shows the results.

Babysitting earnings ($)


What percent of the time did Nicholas earn $25 or less?

Answer 1

25%

Explanation:

From the boxplot Given, an earning of $25 or less is represented on the boxplot as the lower quartile of the distribution which is the point at the start of the box. The lower quartile value is the percentage value up to 25% that is the first 25% of the distribution.

Hence, the percentage required = 25%

Hence, Nicholas earned $25 or less about 25% of the time.
