Conventional wisdom says asprin can reduce fever. A study is conducted to see how effective aspirin is in reducing temperature in children. A sample of 6 children suffering from influenza had their temperatures taken immediately before and 1 hour after administration of aspirin. The results are given below. We would like to conduct a paired differences t-test for this situation. The data follow. Patient Temperature Before Temperature After Difference 1 100.7 98.4 2.3 2 103.7 101.6 2.1 3 101.7 99.9...

I need these questions answered please. 6. YChapter 11) In a pediatric clinic, a study is carried out to see how effective aspirin is in reducing temperature. Five 4-year-old children suffering from influenza had their temperature taken immediately before and 1 hour before administration of aspirin. Assuming the normality of data, we constructed 99% confidence interval for the mean difference in temperature before/after taking an aspirin. The 99% confidence interval is (-0.75, 3.95). If you perform the hypothesis test, what...
