A 90% confidence interval estimate for the population mean constructed with a small sample will have a margin of error that is approximately 90% of the population size n.

Question

A 90% confidence interval estimate for the population mean constructed with a small sample will have a margin of error that is approximately  90% of the population size n.

Quizplus · Accepted Answer

The margin of error for a confidence interval is determined by the sample size, standard deviation, and level of confidence, not the population size. Therefore, we cannot determine the margin of error based on a percentage of the population size.
