9-82.

Do girls read more than boys during the summer? Serena’s class asked 30 parents to estimate how many pages their child read over the summer. They collected the following data. Homework Help ✎

Girls: 10 30 230 130 110 240 150 260 60 230 100 20 50 160 90 pages

Boys: 210 100 0 40 260 240 200 220 190 150 50 100 12 140 40 pages

Make parallel box plots and compare the center, shape, spread, and outliers.

Do girls read more? How many IQRs more do they read? Use the box plots to estimate.

What is similar about the two plots? What is different?

It cannot be determined that girls read more because the difference of 30 pages is less than a fourth of the IQR.
