(PS30) Confidence Intervals for the Population Mean

In this video, we continue our exploration of hypothesis testing methods by introducing a tool known as confidence intervals. We derive the confidence interval for the population mean of a normally distributed population from the perspective of probability and discuss what a confidence interval means, and what it does not mean. We work through a few examples at constructing population-mean confidence intervals given a variety of assumptions, such as when the population standard deviation is known, when its not known, and when the population size is known, for which we introduce the finite population correction factor (fpc) for better estimations. -The Let's Learn, Nemo Community- ►YouTube –    / letslearnnemo   ►Discord –   / discord   ►Twitch –   / letslearnnemo   ►Patreon -   / letslearnnemo   ►Website – https://www.LetsLearnNemo.com #LetsLearnNemo #Probability #Statistics
