yi = Bo + Billi + B2x2i and obtain OLS estimates Bo. B1, and B2. You are primarily interested in the parameter B1. The 95-percent confidence interval for B1 reported as part of the Stata regression output is [-2.709177, 358.7675] The p-value for the hypothesis test Ho : B1 = 0 v.s. H1 : B1 / 0 is 0.054. Suppose you conduct the following hypothesis test at the 5-percent level: Ho : B1 = 400 v.s. H1 : B1 + 400 The outcome of the test is to The value of the OLS estimate B, is Is B1 statistically different from zero (or statistically significant) at the 1 percent level
