Hi Antoine--thank you for the nice article. I think many will find it helpful.

One thing that may be confusing to readers who struggle in statistics and jargon, is in the first example you use a z score for the critical value, and in the second case you use a t score. I think that's important, and perhaps you could add the explanation.

Dear Blaine,

Thanks for pointing it out, it is indeed useful to remind it. I have added a section with the explanation. Do not hesitate to let me know if you see any inconsistency.

Regards, Antoine
