Question

which of the following is the most reasonable estimate of the correlation coefficient? 0.5 0.7 0.9 1.0

Explanation:

The scatter plot shows a strong negative linear relationship: points cluster closely around a downward-sloping line. Correlation coefficients range from -1 to 1; strong negative relationships are close to -1, and the absolute value matches the strength. Among the positive options, 0.9 reflects a strong linear association (the negative sign indicates direction, and the options are positive absolute values of the coefficient).

Answer:

0.9
