Question

Quizplus · Accepted Answer

A confidence interval is a range of values calculated from a sample that is likely to contain the true population parameter with a certain level of confidence. This range is often expressed as a margin of error, which represents the maximum difference between the sample estimate and the true population parameter. Therefore, the correct answer is A) a margin of error. B) the range can be used to describe the confidence interval, but it is not the same concept. C) The standard deviation is a measure of the spread of the data and is not directly related to the confidence interval. D) The difference between two means is a statistic that can be used to form a confidence interval, but it is not the same as the confidence interval itself.
