The superintendent has continued the examination of data and is now interested in attendance rates. Someone suggested to him that there might be a relationshipbetween the number of extra-curricular activities offered at a school and attendance rates, and he wants to see if the data confirms this. Use the data below to help the superintendent determine whether or not there is a relationship between the number of extra-curricular activities offered at a school and its attendance rates.

School	Number of Extra-Curricular Activities Offered	Attendance Rate
1	8	88.8
2	9	96.1
3	8	85.9
4	7	94.2
5	9	85.7
6	7	94.8
7	6	94.8
8	4	82.6
9	5	93.6
10	5	84.8
11	4	98.8
12	8	95.7
13	5	92.4
14	7	93.6
15	7	96.6
16	6	96.0
17	5	93.9
18	9	97.1
19	5	92.8
