Calculate the following stats for 31 (2 decimal places): The t-stat The pvalue The lower bound of the 9596 confidence interval The upper bound of the 95% confidence interval 4. Still using the results from regression i.e. score 17.2+6.2 submission, (2) (2.8) (7) fill out the following table (1 decimal places): id score Submission Predicted score Predicted error/residual 1 47 0 2 901 3 3 67 2 + 4 9 0 5 12 1
