Which of the following statements about confidence intervals are true? I. A 95% confidence interval will contain the true µ 95% of the time. II. If ?(|?̅ − µ| > 3) = 0.035. Then a value of µ that is 3 or less units away from ?̅ will be included in the 99% confidence interval. III. The point estimate ?̅ will be included in a 99% confidence interval.
