Swordfish have a unique "heater organ" that maintains elevated eye and brain temperatures when hunting in deep, cold water.The following graph illustrates the results of a study by Fritsches et al. (2005) that measured how the ability of swordfishretinas to detect rapid motion, measured by the flicker fusion frequency, changes with eye temperature.5040-30-2010-10152025Eye temperature (°C)Whitiock & Schluter.

A gardener applied chemical "Z" to plants in a flower bed. (S)he observed that the plants grew dramatically during the next two weeks. Using only the information from the previous two sentences, write a hypothesis about the effect of chemical "Z" on plants. (Note: Your hypothesis must be a testable statement.) A researcher conducted a series of experiments to test the effect of chemical “Z” on plants. The data from the experiments is summarized in the graph below. (Image of the Graph attached.) Interpret the graph above. What did the researcher learn about the effect of chemical “Z?” Based on the researcher’s graph, what can you conclude about the hypothesis you wrote for Question 7 above?

Freeman and Company The 20 points in the graph were obtained from measurements of 6 swordfish. Can you treat the 20 measurements as a random sample? No, because the selection of the measurements is not independent. Yes, because otherwise the results would not be published. Yes, because the researchers can make a scatter plot only based on the random sample. ONo, because the researchers should have studied at least 10 swordfish. Flicker fusion frequency (hertz)
