Question: For the following data:

a. find the linear regression equation for predicting Y from X

b. use the regression equation to find a predicted Y for each X.

c. find the difference between the actual Y value and the predicted Y value for each individual, square the differences, then add the squared values to obtain SS_residual

d. calculate the Pearson correlation for these data. Use r² and SS_Y to compute SS_residual with Equation 17.11 (SS_residual = (1 – r²) SS_Y)). You should obtain the same value as in part c.
