Calculating beta type 2 error

Web- [Instructor] What we're gonna do in this video is talk about Type I errors and Type II errors and this is in the context of significance testing. So just as a little bit of review, in order to do a significance test, we first come up with a null and an alternative hypothesis. And we'll do this on some population in question. http://sites.saintmarys.edu/~cpeltier/Math241S09/Documents/betarisk1.pdf
