Answer:
In 80% of the tests the number of points scored was less than 49 and in 20% of the tests the number of points scored was higher than 49.
Explanation:
When a value V is said to be in the xth percentile of a set, x% of the values in the set are lower than V and (100-x)% of the values in the set are higher than V.
On a 60 point written assignment, the 80th percentile for the number of points earned was 49. Interpret the 80th percentile in the context of this situation.
The interpretation is that in 80% of the tests the number of points scored was less than 49 and in 20% of the tests the number of points scored was higher than 49.
