Explanation:

Step1: Understand the correlation coefficient

The correlation coefficient \(r = 1\) indicates a perfect positive linear relationship. All the data points lie exactly on a straight - line with a positive slope.

Step2: Analyze \(r=-0.3\)

The correlation coefficient \(r=-0.3\) indicates a weak negative linear relationship. The data points are somewhat scattered around a line with a negative slope.

Answer:

The scatter - plot with all points on a straight - line (left one) has \(r = 1\), and the scatter - plot with points scattered around a line with a negative slope (right one) has \(r=-0.3\).
