0.72	14.6
0.83	15.1
0.57	5.0
0.51	4.1
0.43	3.8
0.37	4.1

(a) explained variation (if necessary, round the the nearest hundredth): Answer

(b) unexplained variation (if necessary, round the the nearest hundredth): Answer

(c) total variation (if necessary, round the the nearest hundredth): Answer

(d) coefficient of determination (if necessary, round the the nearest tenth): Answer
