WebbBecause we are setting $\alpha$, the probability of committing a Type I error, to 0.05, we again reject the null hypothesis when the test statistic $Z\ge 1.645$, or equivalently, when the observed sample mean is 106.58 or greater. WebbOnly 0 heads could yield a type I error, and the probability associated with that is ≈ 0.03. So then the type I error rate would be held to "at most α ", but not equal to α. On the other hand, there are (invalid) analysis strategies that lead to type I error rates that are greater than α, even when p < α (e.g., stepwise selection routines). genshin impact patch 3.5
