What is the covariance between the random variable Y and itself, Cov(Y, Y)? What is the correlation between a random variable and itself? Choose the correct answer below. O A. The covariance between Y and itself is the correlation between Y and itself. The correlation between Y and itself is the covariance between Y and itself. OB. The covariance between Y and itself is the expected value of the mean. The correlation between Y and itself is the variance of Y divided by the covariance between Y and itself. O C. The covariance between Y and itself is the variance of Y. The correlation between Y and itself is 1. OD. The covariance between Y and itself is the standard deviation of Y. The correlation between Y and itself is the variance of Y.
