In Your Experiment in #9, If the Plant(s) Treated with Fertilizer

question 29

Multiple Choice

In your experiment in #9, if the plant(s) treated with fertilizer grew faster, would that prove plants grow faster with fertilizer?

• A) Yes. Clearly that is the case.
• B) No. It would support the hypothesis for that one plant type.
• C) Yes. But you would have to then test whether that is true for other plants.
• D) No. There's no way to know if the fertilizer was making the difference.
• E) Yes. Obviously everyone should use fertilizers when they grow this one type of plant.
