It is moderate degree of relation if 

For two variables x and y. the two regression coefficients are $$b_{x}= -\dfrac{3}{2}$$ and $$b_{y}=-\dfrac{1}{6}$$.
The correlation coefficient between x and y is : 

Coefficient of correlation is the measure of

The regression coefficients of a bivariate distribution are -0.64 and -0.36. Then the correlation coefficient of the distribution is

The correlation coefficient between two variables $$X$$ and $$Y$$ is found to be $$0.6$$. All the observations on $$X$$ and $$Y$$ are transformed using the transformations $$U = 2 - 3X$$ and $$V = 4Y + 1$$. The correlation coefficient between the transformed variables $$U$$ and $$V$$ will be:
