2. Provide the mechanism and potential energy diagram for the reaction of (E) 4- pentene with bromine (B) in dicholormethane (CH.Ch). For the major production stereoisomers are expected and if so if a racemie mixture of mixture of datecomers expected. If more than one stereoisomer is expected then the mechanism s to show the production of only one stereoisomer with a description that clearly describes what the isomeric product(s) would be expected.

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...
