Statistical tests allow us to make statements about the likelihood that the independent variable had an effect, but they cannot prove it definitively. They allow us to weigh the evidence and draw conclusions within a certain level of confidence or probability. Choice A is incorrect because statistical tests alone cannot create an airtight case, as there may be other variables that were not accounted for. Choice C is incorrect because statistical tests cannot prove a hypothesis, they can only provide evidence to support or reject it. Choice D is incorrect because statistical tests cannot prove the null hypothesis, they can only fail to reject it if there is not enough evidence to support the alternative hypothesis.
