If for two variable X and Y the covariance variance of X and variance of y r 40,16 and 256 respectively,what is the value of the correlation coefficient?
Verified Answer
If for two variable X and Y the covariance variance of X and variance ...
Step-by-step explanation:

We know that
r � sdx � sdy = cov( x,y )
Hence,
r � 40 � 16 = 256
r � 20 � 8 = 256
160r= 256
160/256=r
0.625 = r
