Group 1 100 trees control treatment Compare effectiveness 200 maple trees of the new pesticide Group 2 100 trees new pesticide The Asian longhorned beetle kills trees by burrowing within the trunk and branches and disrupting sap flow. A new pesticide will be tested in a major metropolitan city. A statistician designs an experiment for 200 mature maple trees and randomly assigns half of the trees to receive the new pesticide, and the rest to receive a control treatment. Is there any obvious way to improve this experiment to evaluate the effectiveness of the new pesticide? Yes, blocking must be used. Yes, treatment must be randomly assigned. No, basic variations have been accounted for. OYes, a placebo treatment needs to be used. gnment
