Assuming a linear relationship between X and Y,if the coefficient of correlation (r)equals -0.30, A)there is no correlation. B)the variance of X is negative. C)variable X is larger than variable Y. D)the slope (b₁)is negative.

Question

Quizplus · Accepted Answer

The coefficient of correlation (r) being negative indicates that there is a negative relationship between X and Y. A negative relationship means that as X increases, Y decreases. This corresponds to a negative slope (b₁) in a linear relationship between X and Y. Therefore, the correct choice is D.
