You are one of the finalists at a science fair. The scores of the other finalists are 87, 89, 81, 85, 87, 83, 86, 94, 90, 97, 80, 89, 85, and 88. Write an inequality that represents your possible scores if your percentile rank is 80.

Answer 1

sort the scores in order.
Find the lowest score greater than 80% of them. That is the 80th percentile score.

Answer 2

What is "them," exactly?

Answer 3

ummm. The scores. If there are 10 scores, the 80th percentile ends at the 8th score. That is 80% of the scores.

Extra credit: what is "context"?

Answer 4

Never mind, I was confused because there are 14 scores and 80% of 14 is 11.2. I now know that is estimated to the 11th number. Thanks!
