Answer 1

To create scatterplots, plot the points from the tables on a graph where the x-values are on the horizontal axis and the y-values are on the vertical axis.

Scatterplot 1:
- (50, 35)
- (46, 30)
- (80, 75)
- (59, 45)
- (78, 70)
- (64, 50)
- (68, 55)
- (53, 36)
- (70, 62)
- (68, 67)

Scatterplot 2:
- (50, 75)
- (46, 71)
- (98, 90)
- (59, 55)
- (78, 70)
- (64, 100)
- (68, 90)
- (53, 25)
- (70, 40)
- (72, 76)

Scatterplot 3:
- (50, 75)
- (46, 71)
- (90, 100)
- (59, 80)
- (78, 90)
- (64, 82)
- (68, 85)
- (53, 77)
- (70, 87)
- (72, 89)

To determine which scatterplot shows a non-linear association, we can visually inspect the scatterplots. The scatterplot that does not show a linear pattern is Scatterplot 3, as the points do not fall in a straight line.
