A 95% confidence interval for the mean m of a population is computed from a random sample and found to be 9 ± 3. Which of the following is a correct statement? (A) 95% of values sampled are between 6 and 12. (B there is a 95% probability that the true mean is 9 and a 95% chance that the true margin of error is 3. if we took many, many additional random samples and from each computed a 95% confidence interval for u, approximately 95% of these intervals would contain u. D there is a 95% probability that m is between 6 and 12.
