If the null is always false to some degree, then you don’t need to worry about Type I errors because that deals with true nulls. Instead, you’re worrying about Type II errors (failing to reject a false null) because that is applicable to false nulls. An effect exists but the test is not catching it.

WebJul 26, 2015 · $\begingroup$ @Augustin, to elaborate on that, if for example $\mu = 11$ to find $\beta$ the type II error, do I use the same approach. I tried the same and got a value of $2.8665^{-07}$ which still very small. what am I missing?
