Thirty pea seeds were randomly assigned to three groups of ten each. One group was germinated in the presence of chemical A, a second group with chemical B, and the third group served as a control. After five days, the length (in millimeters) of the primary root was measured. We wish to know if either or both of these chemicals affect root growth, and if so, if one is more effective than the other.
