baja_blast  For more, FA 2019 p. 262 goes over Type I and II errors. +

This logic is flawed. They have kept statistical significance level same (alpha - 0.05). p value is probability of committing type 1 error. It is calculated (derived), can't be predecided. alpha-level is pre-decided.

bhangradoc  The P-value is basically the type 1 error, and they keep the p-value the same (at <.05) in both versions of the experiments. By increasing number of patients in the group, they increase power of the study, which reduces type II error. +4
