Given are five observations for two variables, x and y.
xi | 1 | 4 | 11 | 15 | 20 |
yi | 52 | 57 | 48 | 16 | 10 |
a. Compute SSE, SST, and SSR.
SSE [ ] (to 2
decimals)
SST [ ] (to 2
decimals)
SSR [ ] (to 2
decimals)
b. Compute the coefficient of determination
r2. Comment on the goodness of
fit.
[ ] (to 3 decimals)
The least squares line provided an [good,bad] fit;
[ ]% of the variability in
y has been explained by the estimated regression
equation (to 1 decimal).
c. Compute the sample correlation coefficient.
Enter negative value as negative number.
