Let's suppose you were conducting an experiment to see how a type of fertilizer (you have 4 different ones A, B, C, and D) affects the growth rate after 5 weeks of 16 tomato plants in a greenhouse. The first step is to list the treatment levels. You have 16 tomato plants, labeled 1 to 16. First, you write the numbers 1 to 16 on 16 pieces of equal sized paper and place them into a bowl. Next, you write the letters A, B, C, and D on 16 separate pieces of paper (i.e. you'll have 4 A's, 4 B's, 4 C's, and 4 D's) and place them in another bowl. Select one piece of paper from the first bowl and one from the second to get a tomato plant and a fertilizer type. What is the independent variable? the 5 weeks O the tomato plants the growth rate of the tomato plant O the fertilizer type

paper from the first bowl and one from the second to get a
tomato plant and a fertilizer type. What is the independent
