A researcher selects a random sample of college students and measures the number of hours they spend watching television per week and their grade point average. The results are as follows:

	X	Y
Subject #	TV hours	GPA
1	50	1.90
2	20	2.20
3	19	2.40
4	10	3.30
5	7	2.90
6	15	2.50
7	5	3.50
8	40	1.95
9	30	2.00
10	2	3.90
