Terry wants to determine the effect of different colors of light on the growth of plants. He hypothesizes that plants will grow the tallest in green light because plants are green. He sets up four groups of bean plants, with 25 plants in each group. Each of the groups is subjected to a different light source: sunlight, blue light, green light, or red light. All plants receive 12 hours of light per day, 20 mL of water, and 1 gram of fertilizer per week for one month. The height of the plants and number of leaves on each plant is measured weekly. Below is the data Terry collected.
