Answer 1

12

Explanation:

The interquartile range =
`Q_(3)` -
`Q_(1)`

`Q_(3)` is the upper quartile, that is the measure at the right side of the box.

`Q_(1)` is the lower quartile, that is the measure at the left side of the box.

`Q_(3)` = 16 and
`Q_(1)` = 4, thus

interquartile range = 16 - 4 = 12
