Quizplus · Accepted Answer

Confidence intervals provide information on the possible values of the population parameter and the level of certainty associated with the estimation. Based on whether the null value (typically zero) is within or outside the confidence interval, researchers can infer whether there is statistical significance at a certain level of confidence and make a decision on whether to reject or fail to reject the null hypothesis.
