For the following data:

a) Find the regression equation for the 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 ss residual.

d) Calculate the Pearson Correlation for these data. Use r square and ssy to compute ss residual with equation 15.18.
