Question

"The following box plot shows the number of years during which 20 schools have participated in an interschool swimming meet:

(Box plot shown below)*

At least how many schools have participated for 6 years or more?"

I'm stuck on this problem. Box plot questions always trip me! Does anyone out there think they can help me?

Answer 1

Based on the box plot you have given above, the answer would be 20% of the total schools participated for 6 years or more. This is because the part of the box plot wherein it hits 6 years and above is 20%. Thus, if there are 20 schools, then the 20% of it would be 4. In conclusion, there are 4 schools that participated for 6 years or more.
