Â
3.   True or False: If heteroskedasticity is present in our data, then the standard errors of the estimated coefficients are biased and we cannot trust in our hypothesis testing.
Â
Â
4.   True or False: If a regression gave us the following 95% confidence interval for the estimated coefficient: 0.292 to 0.667, we would not be able to reject the null hypothesis that β1 = 0 for a 2-sided t-test at the 5% level of significance.Â
