y
9.5 9.0 11.0 13.0 11.5 12.0 10.0 12.5

x
5.0 4.6 8.5 5.9 7.8 5.3 7.0 7.2
y
12.0 9.0 15.0 11.0 13.0 8.0 14.5 10.0

x
5.0 4.6 8.5 7.8 6.4 6.8 7.0 7.2
y
3.7 2.7 6.5 2.0 5.6 3.0 7.8 6.7

x
5.0 4.6 8.5 7.8 6.8 5.3 7.0 7.2
y

Answer 1

The first scatterplot (x = 5.0, 4.6, 5.9, 7.8, 6.4, 6.8, 5.3, 7.2 with y = 9.5, 9.0, 11.0, 13.0, 11.5, 12.0, 10.0, 12.5) shows a clear linear association (strong positive).
