A 95% confidence interval for the mean u of a population is computed from a random sample and found to be 9+3. In regards to the confidence level, we may conclude that
A) there is a 95% probability that u is between 6 and 12.
B) 95% of values sampled are between 6 and 12.
C) if we took many, many additional random samples and from each computed a 95% confidence interval for y,
approximately 95% of these intervals would contain u.
D) there is a 95% probability that the true mean is 9 and a 95% chance that the true margin of error is 3.
E) all of the above are true.
