Since the scientist conducts an experiment to test her hypothesis that the new chemical cures the disease more effectively than current treatments, it is important she also has a control group. This is different from the experimental group which involves the testing of the cure to mice. The control group will have mice treated with currently available treatment. In this way, she can compare if there was a significant difference between the two groups.
