Two random variables X and Y have means X = 1 and Y = 2, variances o = 4, and o = 1, and the correlation coefficient Pxy = 0.4. New random variables W and V are defined by - V = -X + 2Y and W = X +3Y For the new variables V and W, find: a) The means. (2 points) b) The variances. (4 points) c) The correlation. (2 points) d) The correlation coefficient, Pvw. (2 points)
