a. Find R² and interpret its value.

b. Find R²_a and interpret its value.

c. Test the null hypothesis that ß₁ = ß₂ = 0 against the alternative hypothesis that at least one of ß₁, and ß₂ is nonzero. Calculate the test statistic using the two formulas given in this section, and compare your results to each other and to that given on the printout. Use α = .05 and interpret the result of your test.
