If x and y are any random variables with e(x) = 5, e(y) = 6, e(xy) = 21, v(x) = 9 and v(y) = 10, then the relationship between x and y is a:______.



Answer :

The relationship between x and y is a strong negative relationship.

For this question, we need to determine the correlation coefficient,

Thus,

The correlation coefficient

= (21 - 5*6)/ [tex]\sqrt{9 * 10}[/tex]

= -0.948

The above answer is too close to -1. Therefore correlation coefficient is a strong negative.
