Consider the regression model Y i = ß 0 + ß 1 X 1i + ß 2 X 2i + u r Use Approach #2 from Section 7.3 to transform the regression so that you can use a t-statistic to test
a. ß 1 = ß 2;
b. ß 1 + aß 2 = 0, where a is a constant;
c. ß 1 + ß 2 = 1. (Hint: You must redefine the dependent variable in the regression.)
