The box extends from 1 to 6 on the number line. There is a vertical line at 3.5. The whiskers end at 0 and 8. Above the plot is written Duration of Participation. Below the plot is written Years.

Answer 2

The answer is 6 schools.

In a box and whisker plot, every piece of whisker or box represents 25% of the whole number of schools.

The schools participated 1 year or less are represented by the left part of the whisker. Which stands for 25%.

To make an equation we need to set 100% = 24 and solve for 25% :

`(25)/(100) = (x)/(24)`
Set the denominators equal:

`(150)/(600) = (25x)/(600)`
Remove the denominators and solve:

`150 = 25x \\ \\ x = 6`
