Your concept check question at point 47:35 in the video is confusing. the question is asking "cannot" make which kind of error. The correct answer for a Type 1 is you rejected the null hypothesis when it is true and attributing significance when there is none. So the type of error you "cannot" commit is a Type 2, because you committed a Type 1. Am i on the wrong track or am I missing something? The video at the end made things worse - more confused.
