Problem

Here's a box plot that summarizes the average monthly rainfall of several cities.
A horizontal boxplot is plotted along a horizontal axis marked from 3 to 8, in increments of 0.5, labeled Monthly rainfall (centimeters). A left whisker extends from 3.5 to 5.5. The box extends from 5.5 to 7 and is divided into 2 parts by a vertical line segment at 6. The right whisker extends from 7 to 7.5. All values estimated.
Find the interquartile range (IQR) of the data.
  • Your answer should be
  • an integer, like 6
  • a simplified proper fraction, like 3/5
  • a simplified improper fraction, like 7/4
  • a mixed number, like 1 3/4
  • an exact decimal, like 0.75
  • a multiple of pi, like 12 pi or 2/3 pi
