3. consider the following box plot.

(a) find the interquartile range.
(b) what percent of values is included in the interquartile range?

A) 2.5

B) 50% of the values.

Step-by-step explanation:

A)

    The range of data starts at 2.0 and ends at 4.5 (i know it's a bit hard to tell lol), by subtracting 2.0 from 4.5 you get the interquartile range, 2.5.

B)

    25% of the values are mentioned in the box plot before the median, and 25% of the values are mentioned after the median in the box plot. This together gives you a sum of 50% of the values. Another way to do it is that outside of the interquartile range is 50% of the values.
