When the population standard deviation is unknown, like in this example, we can still get a good approximation by plugging in the sample standard deviation (s).

A confidence interval refers to the probability that a population parameter will fall between a set of values for a certain proportion of times.

Informally, in frequentist statistics, a confidence interval (CI) is an interval which is expected to typically contain the parameter being estimated. History · Definition · Example · Interpretation
