Design an experiment to determine if a solution containing ground-up goldenrod plants has an effect on the growth of radish seedlings. In your experimental design be sure to:
1. State a hypothesis to be tested [25 credits]
2. Describe how the experimental group will be treated differently from the control group [25 points]
3. Identify the type of data that will be collected [25 credits]
4. Explain why the number of seedlings used for the experiment should be large [25 points]
