Question

When helping her little sister with her homework, Monique picked some products randomly from the multiplication chart. The products are represented by the box plot below.What percent of the data is below 16?

Answer 1

Given: The box plot shown in the figure

To Determine: The percent of the data that is below 16

Solution

The given box plot can be interpreted as beow

From the abov, we can sobserve that

$\begin{gathered} Lowest\text{ value}=12 \\ 1st\text{ }Quartile=16 \\ Median=36 \\ Upper\text{ }Quartile=49 \\ Highest\text{ }Value=54 \end{gathered}$

Therefore, the percent of that data below 16 falls in the 1st quartile.

$\text{ }Ist\text{ }Quartile=\frac{1}{4}Of\text{ the data = }\frac{1}{4}\times100\%of\text{ the data = }25\%\text{ of the data}$

Hence, the percent of that data below 16 is 25 %
