WebTrue or False: If a 95% confidence interval contains 1, then 99% confidence interval for the same parameter must contain 1. Justify answer. State true or false. If a 90% confidence interval for the mean is (75.3 to 80.9), we would reject H_0: mu = 70 in favor of H_1: not equal to 70 at alpha = 0.05 WebA confidence interval can be used for hypothesis testing. For example, suppose the null hypothesis θ = θ0 θ = θ 0 for any value of θ0 θ 0. If a confidence interval with confidence level C = 1 −α C = 1 − α contains θ0 θ 0, we fail to reject the corresponding null hypothesis at the significance level α α.
