A research team sought to estimate the model EU') = 0 + [31x + 32w. The variable Ywas the measure of the participant's depression at age 25. The variable w was the participant's depression at age 15. The variable x was the measure of the participant's socialization at age 20. They observed values of y, x, w on 1': = 657 participants. They found that the standard deviation of 1', where the variance estimator used division by n 1, was 32.4; the standard deviation of x was 13 .2; and the standard deviation of w was 19.2. The correlation between 1' and w was 0.68; the correlation between 1' and x was -0.29; and the correlation between :1: and w was 4142. 5. Compute the partial correlation coefcients r13\
