Question

Pls help now !!!!!!!!!!!!!

A fertilizer manufacturer has a new product it is testing to improve the corn yield per acre (see data table). The experiment was performed with equal area, water, corn type, and starting soil conditions for one growing season. Group A was subjected to the new fertilizer and Group B was not provided any fertilizer.
Which statement is the least appropriate hypothesis for this experiment?
A) The more fertilizer added, the greater the corn yield per acre.
B) The use of fertilizer will produce a better corn yield per acre.
C) The type of fertilizer needed for maximum corn yield varies with soil type.
D) Corn yields are consistently the same with and without the addition of fertilizer.

Answer 1

The correct answer is C.) The type of fertilizer will produce a better corn yield per acre.

Step-by-step explanation:

I just took the test and that is the correct answer!:)

Answer 2

C) The type of fertilizer needed for maximum corn yield varies with soil type.

Step-by-step explanation:

Among all the choices, the least appropriate hypothesis would be choice C. This is because the experiment was done using equal areaa, water, corn type, and starting soil conditions. As you can see, the soil was kept constant or was a controlled variable. The only variable that differed between the group was the fertilizer.

Thus, a hypothesis that involves the soil type is not appropriate because it was not what was being tested.
