gabby is working on reducing traffic in her town. last week, she tracked how many cars drove down main street each hour. this box plot shows the results. cars per hour what percent of the time did main street have 100 or more cars per hour? %

Explanation:

Step1: Understand box - plot quartiles

In a box - plot, the box is divided into quartiles. The median (second quartile, Q2) is at the line inside the box. The first quartile (Q1) is at the left - hand side of the box and the third quartile (Q3) is at the right - hand side of the box. The whiskers extend to the minimum and maximum values. Here, the value of 100 is the third quartile (Q3).

Step2: Calculate the percentage

The third quartile represents 75% of the data. So, the percentage of data that is 100 or more is 25% because 100% - 75%=25%.

Answer:

25
