3. consider the following box plot. (a) find the interquartile range. (b) what percent of values is included within the range from part (a)?

Part 1)
Box-and-whisker plots split the data into four sections. Each section contains 25% of the data.

The upper quartile lies at 75%, which is at 4.75.
The lower quartile lies at 25%, which is at 2.25.

Interquartile range = The upper quartile - The lower quartile
Interquartile range = 4.75 - 2.25
Interquartile range =  2.5

Part 2)
Percent of values is included within the range = (2.5 ÷ 6) × 100%
percent of values is included within the range = 0.4166 × 100%
percent of values is included within the range =  41.66%
