Prepare a graph of these data showing the effect of time on tumor production in the two treatments. Put both treatments on the same graph, on two separate lines.

a. On the basis of the shape of the curves, explain the patterns of tumor production in control and experimental mice in weeks 34–52.

b. What is the overall percentage increase in tumors for control versus experimental mice?

c. Which of these two data formats would be more effective in presenting the results of the experiment to the public? Which would be more effective for other scientists?”
