The following ANOVA summary table was obtained from a multiple regression model with two independent variables:

Souce of variation	Sum of square	Degree of freedom	Mean sum of square	F-value
Regression	12.62	2	?	?
Error	0.78	12	?
Total	13.40	14

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.
