Astudy 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 aĆ¢ā¬ā¹ 95% confidence interval for the mean of the Ć¢ā¬ā¹'beforeāĆ¢ā¬ā¹after' differences. does hypnotism appear to be effective in reducingĆ¢ā¬ā¹ pain? in thisĆ¢ā¬ā¹ example, Ī¼d is the mean value of the differences d for the population of all pairs ofĆ¢ā¬ā¹ data, where each individual difference d is defined as the difference in the measurements in centimeters on a pain scale before and after hypnosis. what is the test statistic for this hypothesis test? (round to two decimal places as needed.)
