Book pages
100
150
200
250
300
350
What fraction of the books had 200 or fewer pages?

Answer 1

To find the fraction of books that had 200 or fewer pages, we need to count how many books fall in that category on the box plot.

Looking at the box plot, we see that the lower quartile is at 150 pages and the median is at 250 pages. This means that 25% of the books had 150 pages or less, and 50% had 250 pages or less.

Since 200 pages falls between 150 and 250, we can conclude that 50% of the books had 200 or fewer pages.

Therefore, the fraction of books that had 200 or fewer pages is 1/2 or 0.5.
