Two new chemicals have just been made by one of our colleagues in the medicinal chemistry area. The discoverer thinks that these chemicals will improve memory, so we test these drugs called A and B. In order to test the drugs, we take examinations after ingesting various amounts of the drug. While doing this, we note a toxic effect of these drugs - they make us turn green. We end up with the following data: Dose of Drug (mg) Average of Scores on Exam % of Students that turn Green

A B A B
0 60 60 0 0
1 60 60 0 0
2 65 60 10 0
3 70 60 30 0
4 75 60 50 0
5 80 65 60 0
6 80 70 60 0
7 80 75 60 20
8 80 80 60 50
9 80 80 60 80
10 80 80 60 100
