Solution Steps

Step 1: Observe the scatter plot

The scatter plot shows a positive correlation, as the points tend to increase from left to right. The correlation is moderate, not very strong.

Step 2: Eliminate the negative option

Since the scatter plot shows a positive correlation, we can eliminate -0.9 as a possibility.

Step 3: Estimate the correlation coefficient

The correlation appears moderate and positive, so 0.6 is a reasonable estimate.

Final Answer

0.6
