Question

Quizplus · Accepted Answer

A confidence interval is a range of values in which we are certain that the population parameter lies. It is calculated from a sample statistic and provides an estimate of the range of plausible values for the population parameter. Therefore, option C is the correct statement. Option A is incorrect as we construct a confidence interval around the sample statistic with a certain level of confidence. Option B is incorrect as a confidence interval estimates the range of plausible values for the population parameter, not the sample statistic. Option D is not applicable as there is a correct statement from the options.
