Quizplus · Accepted Answer

The ability of an interval estimate to contain the value of the population parameter is described by the confidence level. The confidence level is the probability that a randomly selected interval estimate will contain the true population parameter. Therefore, a higher confidence level will provide a greater assurance that the interval estimate contains the population parameter. The other options (B, C, and D) are not related to the concept of confidence level.
