Suppose that and are independent and many samples of size n =are drawn and regressions estimated. suppose that you test the null hypothesis that iszero at the 5% level and construct a 95% confidence interval for .yixi411β1β1in what fraction of the samples would the null hypothesis that is zero at the 5% level be rejected? β1a. the null hypothesis would be rejected in 5% of the samples. b.the null hypothesis would be rejected in 90% of the samples. c.the null hypothesis would be rejected in 10% of the samples. d.the null hypothesis would be rejected in 95% of the samples. in what fraction of the samples would the value = 0 be included in the 95% confidence interval for ? β1β1a.5% of the confidence intervals would contain the value = 0.β1b.95% of the confidence intervals would contain the value = 0.β1c.10% of the confidence intervals would contain the value = 0.β1d.90% of the confidence intervals would contain the value = 0.
