Answer:
The set of pepper plants in the fourth box are the control group
Explanation:
The aim of the experiment is to determine the plant fertilizer that will give the most pepper yield
The number of types of fertilizers used under the study = 3 brands
The number of boxes set up for the experiment = 4 boxes
The number of pepper plants planted in each box = 3 sets
The fertilizers applied to each box = One different type for each of the first three box
The type of fertilizer applied to the fourth box = No fertilizer
The control group is the group to which the effect of the other groups subject to the experimental treatment are compared, and the group not subject to the treatment of the experiment.
Therefore;
The set of pepper plants in the fourth box are the control group.
