1. Calculate the t-statistic for a test comparing the coefficient on X to a null hypothesis value of 0 2. Construct the 95% confidence interval for the coefficient on X. (use 1.96 as the critical value) 3. Is the coefficient on X statistically significantly different from 1 at the 95% level? Yes or no. CAREFUL: this question is asking you to use a null hypotheses value of 1, not 0.
