Answer:
The covariance is 6
Step-by-step explanation:
- The covariance between X and Y indicates how the values of X and Y move relative to each other.
- If the value of X and Y are both large or the value of X and Y are small, the covariance is positive.
- If the value of one is more than the other, the covariance is negative.
- The formula of covariance is given by
- Given, XY=350, E(X) =4, E(Y)=16
- covariance is
