D) a confidence interval.

Question

Quizplus · Accepted Answer

A confidence interval is the best choice for getting a range of mean differences that could be expected in the future. A confidence interval provides a range of possible values for the true population mean difference, along with a level of confidence that the true population mean difference falls within that range. This information is useful for understanding the practical significance of the obtained mean difference and for making predictions about the mean difference in future samples.
