A 95% confidence interval for mean, µ, of a population computed from a random sample is found to be 9 ± 3. Based on this, which of the following statements is true?
A) The probability that the value of x-bar obtained from a random sample of the same size will be between 6 and 12 is 0.95.
B) Ninety-five percent of 95% confidence interval estimates of this µ calculated from random samples of the same size would be (6, 12).
C) We can be 95% sure that the value of µ is between 6 and 12 because 95% of the confidence intervals calculated this way contain the true value of µ.
D) The probability that µ has a value between 6 and 12 is 0.95.
