The correct answer is C. A set of ranges contains the population mean with 95% certainty. A set of ranges contains the population mean with 95% certainty. Rationale:This statement accurately describes a 95% confidence interval. It means that if we were to take 100 different samples and compute a confidence interval for each sample, we would expect about 95 of the…

Explanation

A set of ranges contains the population mean with 95% certainty. Rationale:This statement accurately describes a 95% confidence interval. It means that if we were to take 100 different samples and compute a confidence interval for each sample, we would expect about 95 of the intervals to contain the true population mean.
