Question

Quizplus · Accepted Answer

A confidence interval is used to estimate the range in which we believe the true population parameter lies. The sample is used to create the interval, but the interval is providing information about the population, not the sample. A census refers to gathering data from an entire population, so it is not directly related to the idea of a confidence interval. Random and target are not appropriate choices in this context.
