A student is studying the effects of sunlight on tomato plants. She chooses 6 tomato plants, making sure that each of them receives the same amount of water and fertilizer each day. She gives one plant 0 hours of sunlight each day, with the other 5 plants receiving 1, 3, 5, 7, and 9 hours of sunlight. At the end of the experiment, she has people try a tomato from each plant and has them rank the fruits by their sweetness. She also records the total number of leaves produced on each tomato plant.
