The correct answer is D because in statistical tests, especially in the context of experimental research, the goal is to determine whether the independent variable probably caused changes in the dependent variable. This is done by rejecting or failing to reject the null hypothesis, which states that there is no effect or difference, thereby inferring the likelihood of the experimental hypothesis being true. However, statistical tests do not definitively prove causation or the truth of hypotheses; they assess the probability of observing the data if the null hypothesis were true.
