8-20.

There are five students of different ages. Their median age is 13 years. Homework Help ✎ What are two possibilities for the ages of the three oldest students?

If each student is a different age, how many students must be younger than 13?

In complete sentences, describe what a median is to another student in the class. Pretend that the student was absent the day you learned about medians.

The median is the middle number of a data set ordered from least to greatest.

If 13 is the median age in a set of five students, the two oldest students must be older than 13.

2 students
