I need help answering these questions.

Suppose you have joint random variables X and Y. It is found that COV(X, Y) = 0.8, Var(X) = 5, and Var(Y) = 6. Based on the covariance, is there a positive relationship, a negative relationship, or no linear relationship between the variables? O No Linear Relationship O Negative O Positive Find the value of the correlation coefficient. Round your answer to 3 decimals.
