The adjusted coefficient of determination was as follows:
R-bar2 = .91
a. Find and interpret a 99% confidence interval for β1.
b. Test, against the alternative that it is positive, the null hypothesis that β2 is 0.
c. Find the coefficient of determination.
d. Test the null hypothesis that β1 = β2 = 0.
