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 r^2 and SSy to compute SS residual
