You take two samples from a population. One sample drinks a glass of quinine, the other drinks a glass of Gatorade. After 15 minutes, you time each member of the two samples on a mirror-drawing task. You get the following results (in seconds):

Quinine	Gatorade
4.5	5.3
5.2	5.1
3.7	4.6
4.1	4.1
4.4	4.5
3.9	4.8
4.6	4.0
4.8	5.5
