A study was carried out on the effectiveness of Reiki therapeutic touch to manage pain in cancer patients. Pain was assessed twice for each of the 14 cancer patients: once before and once after Reiki touch therapy. For each of the 14 subjects, the difference between each pair of pain scores was recorded (difference = after - before). The 14 differences have a mean of -1.86 and a standard deviation of 1.69. 1. Compute a 95% confidence interval for the true population mean change in pain scores. (give answers to 4 places past decimal) lower bound: upper bound: Submit Answer Tries 0/99 2. Which one of the following is the correct interpretation of the confidence interval in part 1 above? O The most likely mean difference in pain score for any cancer patient is -1.86. O There is a 95% chance that the above confidence interval will contain the true mean difference. O The true mean difference in pain score in all cancer patients is -1.86. O with repeated sampling, your confidence interval will contain the true mean difference 95 out of 100 times. Submit Answer Tries 0/99 3. You are asked to test for a signifcant change in pain scores. Based on the confidence interval you constructed in part 1 above, would you reject the null hypothesis that Reiki touch therapy has no effect on pain score?
