The Student Government Association at Southwestern State University wanted to demonstrate the relationship between the number of beers a student drinks and their blood alcohol content (BAC). A random sample of 18 students participated in a study in which each participating student was randomly assigned a number of 12-ounce cans of beer to drink. Thirty minutes after consuming their assigned number of beers a member of the local sheriff's office measured their blood alcohol content. The sample information is reported below.

Student	Beers	BAC	Student	Beers	BAC
1	6	0.1	10	3	0.07
2	7	0.09	11	3	0.05
3	7	0.09	12	7	0.08
4	4	0.1	13	1	0.04
5	5	0.1	14	4	0.07
6	3	0.07	15	2	0.06
7	3	0.1	16	7	0.12
8	6	0.12	17	2	0.05
9	6	0.09	18	1	0.02

(a) There are two variables in this data: number of beers and BAC. Which variable is the dependent (Y) variable?
