You want to compare the brightness and tanginess of strawberries grown with three amounts of a new fertilizer (none, half the recommended amount, and the full recommended amount). You allocate 13 strawberry bushes to receive each amount of fertilizer, assigning them at random. What is the factor and its levels? How might the response be measured?What is the factor and its levels?
A. The factor is the amount of fertilizer. The levels are the 1/3 strawberry bushes.
B. The factor is the amount of fertilizer used on each bush. The levels are the different amounts of fertilizer (none, half the recommended amount, and the full recommended amount).
C. The factor is the type of fruit being tested. The level is the number of bushes that are in the experiment.
D. The factor is the measured brightness and tanginess of each strawberry. The level is how each strawberry rates on brightness and tanginess.
