A 99% Confidence Interval for the Mean μ of a Population

Multiple Choice

A 99% confidence interval for the mean μ of a population is computed from a random sample and found to be 6 ± 3. What may we conclude from this estimate?

A) There is a 99% probability that μ is between 3 and 9.
B) The true mean is 6 and the true margin of error is 3, both with 99% probability.
C) If we took many, many additional random samples, and from each computed a 99% confidence interval for μ, approximately 99% of these intervals would contain μ.
D) All of the above
