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