I used the following correlation matrices, A and B, in Study Suggestion 3 in Chapter 5. This time, do the following calculations using matrix algebra. Compare the results with those calculated in Chapter

(a) Calculate the inverse of the correlation matrix of the independent variables, X_I
and X₂, for A and B.

(b) Multiply each of the inverses calculated under (a) by the column of the zero-order correlations of the X's with Y. What is the meaning of the resulting values?

(c) Multiply each row obtained under (b) by the column of the zero-order correlations of the X's with Y. What is the meaning of the resulting values?
