Page 143, 2.6.6*. Let X₁, X₂, and X3 be three random variables with means, variances, and correlation coefficients of (X₁, X₂), (X₁, X3), (X2, X3) denoted by M₁, M2, M3; 0²1, 0²2, 0²3; and P12, P13, P23, respectively. For constants b2 and b3, suppose E(X₁-M₁ X2, X3) = b₂(x2-M₂)+b3X3 Determine b₂ and b3 in terms of the means, the variances and the correlation coefficients.

Page 143, 2.6.6*. Let X₁, X₂, and X3 be three random variables with means, variances, and correlation coefficients of (X₁, X₂), (X₁, X3), (X₂, X3) denoted by µ₁, µ2, M3; 0²1, 0²2, 0² 3; and P 12, P13, P23, respectively. For constants b2 and b3, suppose E(X₁-M₁ X2, X3) = b₂(x2−µ₂)+b3X3 Determine b2 and b3 in terms of the means, the variances and the correlation coefficients.
