For the following data: Find the regression equation for predicting Y from X (Provide your work). Use the regression equation to find a predicted Y for each X. Find the difference between the actual Y value and the predicted Y value for each individual, square the differences, and add the squared values to obtain SSresidual. Calculate the Pearson correlation for these data. Use r2 and SSy to compute SSresidual. You should obtain the same value as in part c. Now...
