If X and Y Are Any Random Variables with E(X)= $\sqrt { V ( x ) V ( y ) }$

Short Answer

If X and Y are any random variables with E(X)= 3, E(Y) = 2, E(XY) = 12, V(X) = 16 and V(Y) = 25, then the relationship between X and Y is a: Hint: corr(X,Y) =( E(xy) - E(x)E(y))/ $\sqrt { V ( x ) V ( y ) }$ $\begin{array}{|l|l|}\hline A&\text { weak negative relationship. }\\\hline B&\text {strong positive relationship. }\\\hline C&\text { strong negative relati on shi \( \mathrm{p} \).}\\\hline D&\text { weak negative relati onship.}\\\hline \end{array}$
