To select the best answer for this exercise which example is this.
Answer to Problem 95E
Option (c) is the correct option.
Explanation of Solution
In this question, it is given that we do not know whether the difference is due to the superiority of variety one to the effect of this year’s drought. Thus, confounding is when a variable whose effect is not accounted for in an experiment has an effect on the results. The drought was not a variable tested for, it confounds. Thus, this is an example of matched pairs design. The option (c) is the correct option.
