You construct a​ 95% confidence interval for a population mean using a random sample. The confidence interval is 24.9<μ<31.5  Is the probability that μ is in this interval​ 0.95? Explain.   Choose the correct answer below.     A. Yes. The probability that μ is in this interval is 0.95.   B. No. With​ 95% confidence, the mean is in the interval ​(24.9​,31.5​).   C. No. If a large number of samples are taken the probability that the mean is in the interval is 0.95.   D. No. Approximately​ 95% of the sampled data will fall in the confidence interval.
