Statistics 101: Two Populations, t-test with Hypothesis
In this video, we explore multiple populations by finding a confidence interval for the mean difference between two populations. For this case, we do not know the two populations' standard deviations. This is called an independent samples t-test.
We learn how to find the standard error, margin or error, and confidence interval for the difference between two populations. Illustrations and examples are provided. Enjoy!
