Find P5, P10, and P20 for the ACT scores.
---------------------
I'll find P5.

1st: Put the data in ascending order from minimum to maximum
2nd: Find the locator for P5:
5%(25) = (5/100)25 = 5/4 = 1.25
Round up to the next whole number:
locator = 2
---
3rd Find P(5) which is the 2nd data element starting at the min.
----
P(5) = 16
