. Consider the arbitrary random vector X? = [X1, X2, X3, X4,X5] with mean vector µ ? = [µ1, µ2, µ3, µ4, µ5]. Partition X into X= X(1) X(2) where X(1) = X1 X2 and X(2) = ?? X3 X4 X5 ? 3. Consider the arbitrary random vector \( \mathbf{X}^{\prime}=\left[X_{1}, X_{2}, X_{3}, X_{4}, X_{5}\right] \) with mean vector \( \mu^{\prime}=\left[\mu_{1}, \mu_{2}, \mu_{3}, \mu_{4}, \mu_{5}igh 1 answer
