28. By looking at the given shaded region, it seems that option D is correct because the values in option D only seems to be calculated SSR and SST. To be sure, we can run regression on the excel data set and can find the exact SSR and SST values.
29. Option C is corrrect. The answer would be Student 8 because in the residual output, the error difference in case of student 8 is lowest. Hence, performance of student 8 would be the closest prediction.
30. Option A is correct. To evaluate the correlation between X and Y, t test is used and then R^2 tells further the strength of model.
