Quizplus · Accepted Answer

A region of scores estimated to include a population parameter such as the population mean is called an interval estimate. A confidence interval is a specific type of interval estimate that also includes a level of confidence or probability. Therefore, both options B and C are correct. A point estimate is a single value estimate of a population parameter, such as the sample mean being used to estimate the population mean, but it does not provide a range or interval.
