The statistics of n=22 and s=14.3 result in this​ 95% confidence interval estimate of ​σ: 11.0<σ<20.4. That confidence interval can also be expressed as​ (11.0, 20.4). Given that 15.7+_4.7 results in values of 11.0 and​ 20.4, can the confidence interval be expressed as 15.7+_4.7 as​ well? Choose the correct answer below. A. Yes. In​ general, a confidence interval for σ has s at the center. B. Yes. Since the​ chi-square distribution is​ symmetric, a confidence interval for can be expressed as 15.7+_4.7. C. No. The format implies that s​=15.7, but s is given as 14.3. In​ general, a confidence interval for σ does not have s at the center. D. Not enough information
