(SUBTOTAL 15 POINTS) TAs PLEASE CHOOSE ONE OF THE FOLLOWING FOR QUESTION #1 A. (7 points) In a case of school spirit gone too far, you decide to raise a colony of super yellow jackets for an assault on Michael Vick’s Academy of Bulldog Warfare. To fully prepare them, you have cre- ated a formula called YJ1990 that should help the yellow jackets grow up bigger and stronger than nor- mal yellow jackets. In the past, others have raised “super” colonies by adding steroids to the yellow jacket food, but you suspect that YJ1990 will work better. Devise an experiment to test if YJ1990 will if YJ1190 will enhance the growth of yellow jackets. Be sure to use sound experimental design prin- ciples and explicitly state everything that is a part of your experimental design. You will test the effect- iveness of YJ1190 by testing the changes in the mass of the yellow jackets. Hypothesis: Yellow jackets on steroidal formula will grow bigger than ones without formula Null: No effect Positive: Steroids Negative: let them be normal Experiment: Divide into four treatments; one colony for close relation. Only thing different is diet. Monit- or growth over period of time. Record data Graders: 1 point for each of the above items except for experimental design, which is 2 points. B. (8 points) Below is a table that represents the mass of five members from each of two different colo- nies of yellow jackets over the course of four weeks.
