What percent of the runners were between 20 and 45 years old?
%

Answer 1

To find the percent of runners between 20 and 45 years old, we need to count the number of runners within that age range.

From the box plot, we can see that there are 4 runners with ages 25, 35, and 45 (but not including 20 as it is not shown in the data), out of a total of 6 runners.

Therefore, the percentage of runners between 20 and 45 years old is (4/6) * 100 = 66.67%.

So, 66.67% of the runners were between 20 and 45 years old.
