Quizplus · Accepted Answer

A confidence interval provides a range of values within which the true population proportion is likely to lie with a certain degree of confidence, typically 95% or 99%.

The level of confidence only refers to the likelihood that the true value falls within the interval, not to the certainty that it does.
