(Use the fоllоwing infоrmаtion for the next 2 questions) Dr. Sully is а mаrine biologist who researches the association between clownfish and two anemone species. Her observations have shown that clownfish are found in both the blue anemone species and the orange anemone species. While the blue and orange anemone species are very similar, the orange anemone species produces a much more toxic venom than the blue anemone species. Clownfish are coated with a mucus layer that protects them from venom of some anemone species, but not all species. Dr. Sully has also observed that there appear to be more clownfish living in the blue anemones than the orange anemones. To test differences in clownfish usage of the different anemone species, she measures the visitation rate of clownfish (# of clownfish visits/hour) to 10 blue anemones and 10 orange anemones. She then compares mean visitation rates between the 2 groups. Which of the following would be the best prediction for this research?
