Suggestions on notation from Philippe B. #3
Description
Via email (Sep. 18, 2018):
On module 2, lesson 1. I would recommend you distinguish your notation (and explain the convention in the text) between statistics for population (uses greek symbols) and for a sample (uses roman symbols). You do it without mentioning it for the population standard deviation (but your formula should have mu inside not x bar). It might be good to also do it for the mean.
