study was conducted to measure the effectiveness of hypnotism reducing pain. The measurements are centimeters on a pain scale before and after hypnosis. Assume that the paired sample data are simple random samples and that the ifferences have a distribution that is approximately normal. Construct a 95% confidence interval for the mean of the "before-after" differences. Does hypnotism appear to be effective in reducing pain? Before After 5.9 6.2 5.5 2.6 Construct a 95% confidence interval for the mean of the "before-after" differences. <<(Round to two decimal places as needed.) oes hypnotism appear to be effective in reducing pain? 11.6 7.2 OA. No, because the confidence interval does not include zero and is entirely greater than zero. OB. No, because the confidence interval includes zero. OC. Yes, because the confidence interval includes zero. 12.5 8.6 8.1 8.8 9.7 6.4 5.4 3.1 7.2 2.3 D
