(c) Suppose that the heteroskedastic robust standard error on the estimated B, coefficient from the regression above is 0.25. Carry on a two-sided hypothesis test on the null hypothesis that B1 = 0 and report your decision, based on a 1% significance level. Next, repeat the same exercise but now using the standard error that is not adjusted for heteroskedasticity, which in this case is 0.19. What would be your decision now, again based on the same 1% significance level? Discuss the results
