Question

The following box and whisker plot represents the weight of seven boys:

What percentage of boys weigh more than 80 kg?

• A. $25\%$
• B. $50\%$
• C. $30\%$
• D. $10\%$

Answer 1

The correct option is A $25\%$

A box and whiskers plot is constructed from five values: minimum number, lower quartile, median, upper quartile, and maximum number.

Each section of the Box and Whiskers plot contains approximately 25% of the data for that set.


Since, the upper quartile of the given data is 80 kg, so $25\%$ of the boys weigh more than 80 kg.
