Researchers studies the effect of a fertilizer on radish sprout growth. They randomly selected some radish seeds to serve as controls, while others were planted in aluminum planters to which fertilizer sticks were added. Other conditions were held constant between the two groups. The following table shows a summary of the heights of plants (in cm) 2 weeks after germination
