Solution:

a) Little or no association: Scatterplot (1) does not show any pattern. Therefore, it shows little or no association.

b) Negative association: Scatterplot (4) shows a downward tendency pattern. Therefore, it shows a negative association.

c) Linear association: Scatterplot (2) and (4) show upward and downward tendency patterns respectively. Therefore, it shows a linear association.

d) Moderately strong association: Scatterplot (3) shows a parabolic nature. Therefore, it shows a moderately strong association.

e) Strong association: Scatterplot (2) and (4) show a linear upward and downward tendency. Therefore, it shows a very strong association.
