Answer

Answer:

B. -0.17, negative correlation

Explanation:

Step1: Recall correlation coefficient concept

The correlation coefficient $r$ ranges from - 1 to 1. If $r>0$, it's positive correlation; if $r < 0$, it's negative correlation; if $r$ is close to 0, it's no correlation.

Step2: Analyze given value

Here $r=-0.17$. Since $r=-0.17<0$, it indicates a negative correlation.
