Given are five observations for two variables,  and .

The estimated regression equation for these data is
yhat = 1.3+2.5x.

a. Compute SSE, SST, and SSR using the following equations (to 1 decimal).

b.
Compute the coefficient of determination
rsquare  (to 3 decimals).

Does this least squares line provide a good fit?

- Select your answer -No, the least squares line does not produce much of a fitYes, the least squares line provides a very good fitItem 5

c. Compute the sample correlation coefficient (to 4 decimals).
