    Which of the following descriptions of confidence interval is correct? (Select all that apply)

    a. If a 99% confidence interval contains 0, then the 95% confidence interval contains 0
    b. If a 95% confidence interval contains 0, then the 99% confidence interval contains 0
    c. If a 99% confidence interval contains 1, then the 95% confidence interval contains 1
    d. If a 95% confidence interval contains 1, then the 99% confidence interval contains 1

    a. If a 99% confidence interval contains 0, then the 95% confidence interval contains 0
    c. If a 99% confidence interval contains 1, then the 95% confidence interval contains 1

    The lower the confidence interval, the wider the range, so if a higher confidence interval contains a point, a lower confidence interval will contain that point as well.
