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 do you expect? At 99% confidence level, there is no significant difference in mean temperature before/after taking aspirin. At 99% confidence level, there is significant difference in mean temperature before/after taking aspirin. a. b. c. No enough information d. None of above
