Answer 1

To create scatterplots, we need to plot the points with the x-values on the x-axis and y-values on the y-axis.

Scatterplot 1:
- x: 50, 46, 90, 59, 78, 64, 68, 53, 70, 72
- y: 75, 71, 100, 80, 90, 82, 85, 77, 87, 89

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

Scatterplot 3:
- x: 50, 46, 80, 59, 78, 64, 68, 53, 70, 68
- y: 90, 100, 57, 80, 60, 75, 72, 82, 70, 67

Scatterplot 4:
- x: 50, 46, 80, 59, 78, 64, 68, 53, 70, 68
- y: 35, 30, 75, 45, 70, 50, 55, 36, 62, 67

To determine which scatterplot shows a non-linear association, we need to analyze the pattern of the points. A non-linear association implies that the points do not form a straight line.

From the scatterplots, it appears that Scatterplot 3 has a non-linear association because the points do not form a straight line.
