Answer 1

To create scatterplots, we need to plot each pair of x and y values on a graph.

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

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

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

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

After graphing the data, we can determine that scatterplot A shows a non-linear association.
