7. Shown below is a partial computer output from a regression analysis.
(see attached file)
a. Use the above results and write the regression equation.
b. Compute the coefficient of determination and fully interpret its meaning.
c. At a = 0.05, test to see if there is a relation between X1 and Y.
d. At a = 0.05, test to see if there is a relation between X3 and Y.
e. Is the regression model significant? Perform an F test and let a = 0.05.
The solution addresses partial computer from a regression analysis.
