The dependent variable is a little less exciting than that, and is just how many ears of corn per plant were produced. Also, while 5 is correct, the variable of Rapid Red Fertilizer was the value of the variable, not the variable itself. Your initial statement was more accurate: For number 7 your answer is correct though I hate this question because it implies that there is only one 'controlled' variable, when in reality there are tons though I'd be more specific Number 8 is the only one where I think you're a little off.
If the control ends up producing more ears of corn per plant, then we can make a valid guess that Rapid Red Fertilizer does have an effect on the plants Not only does Rapid Red Fertilizer fail to do what it advertises, it decreases the yield per plant instead of increasing it.
In order for the fertilizer to have no effect on the growth and production of the corn plants when compared to using a standard fertilizer , you would have to have an equal yield of corn per plant for both the control group and the experimental group.
