The change in systolic and diastolic blood pressure values of the participants represents the a. independent variable b. dependent variable c. hypothesis d. theory e. control group 2. These data are from two enclosures: one with light-colored soil (left), and one with dark-colored soil (right). How many dark brown mice were caught in the light-colored soil enclosure on a moonlit night? a. 12 b. 17 C. 19 d. 37 Number of mice caught 40- 35 30 15 10 5 0 Light coat Dark coat Number of mice caught 40 35-4 25 10 5 0 Light coat Dark coat Full moon No moon Full moon No moon B: Dark-colored soil A: Light-colored soil Data from D. W. Kaufman, Adaptive coloration in Peromyscus polionotus: Experimental selection by owls, Journal of Mammalogy 55:271-283 (1974). 3.

A friend of yours calls to say that his car would not start this morning. He asks for your help. You say that you think the battery must be dead. If so, then jump-starting the car from a good battery will solve the problem. In doing so, you are a. testing a theory for why the car will not start b. making observations to inspire a theory for why the car will not start c. stating a hypothesis and using that hypothesis to make a testable prediction d. comparing multiple hypotheses for why the car will not start
