Quizplus · Accepted Answer

Statistical significance means that the differences found in the sample may be assumed to exist in the population. It does not necessarily mean that the differences are present in all samples, as option A suggests. Option B is incorrect because it uses the term "assumed" which implies a lack of certainty. Option D is incorrect because statistical significance does not guarantee that the differences found in the population will be present in the sample. Option E is also incorrect because statistical significance is a statistical concept and does not necessarily have direct implications for managerial decision-making.
