If two random variables X Y are independent then according

If two random variables (X & Y) are independent, then according to Equation (7.41) what is the predicted value of Y? E_y [Y]/var (x) x - E_x [x] E_y [Y] E_x [x] True or False: If two random variables are positively correlated then one of the variables must be a cause of the other. True False If X[n] is a WSS process with the following mean and autocorrelation sequence mu = 2, r_X[k] = (0.5)^|k|,and we observe x[5] = 3, what is the predicted value of x[7] (using optimal linear prediction)? 2.75 3.25 3.5 2 0
