It is because it is a statistical problem that you can’t replace “all” with “most”. The F-value threshold was calculated assuming “all”, not “most”. You’d need a different threshold if you don’t mean “all”.
Also, the people I am complaining about explicitly use “all” when they interpret medical journal articles in which a test for an effect was failed as having proven that the effect does not exist for any patients.
