Q.4 A random vector (X, Y, Z) has joint density given byf (x, y,z) = k exp [− 1/2 (2x2 − 2xy + y2 + z2 + 2x − 6y) .1. Compute k. 2. Compute the expectations P(X), P(Y ) and P(Z). 3. Compute the density of the random vector (X, Z). 4. Compute the correlation coeffificient between X and Z and between X and Y . 5. Let W = X + Z; compute the probability density of W. |
