To determine which correlation coefficient is the strongest, we look at the absolute values of the coefficients.
- For \( r = -0.9870021 \), the absolute value is \( 0.9870021 \).
- For \( r = 0.9870013 \), the absolute value is \( 0.9870013 \).
Since \( 0.9870021 \) is greater than \( 0.9870013 \), the strongest correlation is with \( r = -0.9870021 \).
Therefore, the answer is:
**1** for \( r = -0.9870021 \).
- For \( r = -0.9870021 \), the absolute value is \( 0.9870021 \).
- For \( r = 0.9870013 \), the absolute value is \( 0.9870013 \).
Since \( 0.9870021 \) is greater than \( 0.9870013 \), the strongest correlation is with \( r = -0.9870021 \).
Therefore, the answer is:
**1** for \( r = -0.9870021 \).
