A 99% confidence interval for the mean μ of a population is computed from a random sample and found to be 6 ± 3. We may conclude that:
A. there is a 99% probability that μ is between 3 and 9.
B. there is a 99% probability that the true mean is 6, and there is a 99% chance that the true margin of error is 3.
C. All of the above.
D. 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
