Question: 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,

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.
