Answer
Answer:
A. -0.83
Explanation:
Step1: Observe data trend
The data points show a downward - sloping trend, indicating a negative correlation. So, we can eliminate the positive values 0.21 and 0.83.
Step2: Assess strength of correlation
The points are relatively close to the regression line, suggesting a strong negative correlation. - 0.83 represents a strong negative correlation while -0.21 represents a weak negative correlation. So the correlation coefficient is -0.83.
