Extracted text: A study was conducted to measure the effectiveness of hypnotism in 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 differences 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 6.6 2.2 6.1 10.6 9.0 4.8 2.9 5.3 After 6.2 2.3 7.6 8.1 8.1 6.4 3.4 2.4 Construct a 95% confidence interval for the mean of the "before - after" differences. <><(round to="" two="" decimal="" places="" as="" needed.)="" ut="" help="" me="" solve="" this="" view="" an="" example="" get="" more="" help="" -="" w-="" clear="" all="" check="" answer="" ip="" ma="" ng:="" floor:="" departmer="" default="">
