It is hypothesized that in a graduating class of 750 students, there will be a strong positive correlation between that student’s class rank, and their rank in a schoolwide debate competition. For a sample of n=10 students, the class rank and debate competition ranks are as follows:

Class Rank (X)	Rank in Schoolwide Debate Competition (Y)
2	9
3	8
4	7
5	6
6	5
7	4
8	3
9	2
1	10
10	11
