Suppose Raquel has joint random variables X and Y. It is found that COV(X, Y) and Var(Y) = 7. = -0.8, Var(X) = 2, 1. Based on the covariance, can Raquel state if there a positive relationship, a negative relationship, or no linear relationship between the variables? Negative No Linear Relationship Positive 2. What is the difference between covariance and the correlation coefficient? No computation required. Suppose Raquel has joint random variables X and Y.
