which correlation coefficient is most likely to describe the relationship between brushing ones teeth and the number of cavities one gets?
+.45
-.62
+.83
-.08

Explanation:

A negative correlation coefficient indicates an inverse relationship. Brushing teeth more (independent variable) would likely lead to fewer cavities (dependent variable), so a negative coefficient is expected. A value of -0.08 is close to 0 (weak relationship), +0.45 and +0.83 are positive (direct relationship which is incorrect here). -0.62 shows a moderate - strong negative relationship which is reasonable as brushing teeth affects cavity occurrence.

Answer:

-.62
