Question: For the following data:

a. Find the 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, and add the squared values to obtain SSresidual

d. Calculate the Pearson correlation for these data. Use r² and SSy to compute SSresidual with Equation 15.18. You should obtain the same value as in part c.
