Hypothesis Testing for the Population Proportion
In this video we'll look at how to run a full hypothesis test, from beginning to end, or a proportion, instead of a mean. We'll also consider what it looks like to run this as a one-tail test and as a two-tail test.
Significance Level and Type I and II Errors
The level of significance is the alpha value of our test, and it also represents the probability of making a Type I error. A Type I error occurs when we mistakenly reject the null hypothesis when the null hypothesis is actually true.
