MATH 225N Week 6 Discussion: Confidence Interval (2020) complete solution help.

Document Content and Description Below

Answer 1 Since I have become a nurse I have personally felt the intense low back pain that once use to be just a one-sided conversation. Low back pain (LBP) is a significant health concern worldwide... . Although pharmacological therapies have been shown to be successful in reducing pain, each one carries a risk. My study consist of non-pharm approach to reducing pain. Because of time and cost I escheated the effects of pain and nonpharmacological intervention, such as music, breathing, acupuncture and massage to name a few. I work in surgery and we play music for patients. In the article Medical statistics: Hypothesis tests and Estimation, discussed the relative effectiveness of acupuncture and massage as treatments for chronic low back pain in patients presenting to primary care. The study showed the disparity in pain ratings between the two groups. As we have been learning these pass weeks, it is not possible to be 100% sure of the range within which the population estimate will fall, so a degree of trust is added to the set of values. The 95% confidence interval for the mean difference in pain scores of 8.1 is (1.2,15.0). 90% confidence interval (2.3,13.9) which is narrower. 99% confidence interval (-1.0,17.2) is wider than the 95% CI. Not having a value 0 between two of the ranges will not have a significant difference in mean pain scores. Thus, by widening the range of values this increase the uncertainty and the interval now includes 0 therefore it is possible, this confidence level, now has no difference in mean pain score between the two groups. As we learned in Week 6 lesson, it states confidence intervals in medicine include a range within which test results or measurements may be predicted (chamberlain, 2020). Although pharmacological therapies have been shown to be successful in reducing pain, each one carries a risk of potentially severe side [Show More]
