i) Determine the mean sum square due to regression, the mean sum square due to error and F-value.
ii) Test the significance of overall model at 5% level of significance.
iii) Compute coeff of determination and interpret its value.
iv) Find standard error of estimate.
A worked answer is on its wayMeanwhile, read the Statistics II notes for this topic.
