How To Find The Z Score, Confidence Interval, and Margin of Error for a Population Mean
This statistics video tutorial explains how to find the z-score that will be used to find the confidence interval and margin of error for a population mean. This video contains 2 example problems in which you're asked to find a 90% and 95% confidence interval given the population standard deviation, sample mean, and sample size. By the way, the margin of error is also known as the error bound. This video also explains the difference between the confidence interval and the confidence level. It also discusses the meaning of the greek symbol alpha as it is used in this context.
