Ana found out that his cabbage carden is infested with bugs. He decided to use a dilution of detergent, but he did not know the right amount of dilution of detergent that will be effective as insect repellant without harming the plant itself. He created an experiment plan with 4 set up including the control set up. A. What should be the number of plant sample to use in every set up? B. What should be the percent dilution of treatments of every set up? C. Number of applications per day for 1 week in each set up?
