:: @CR0617470: no, the OP specified "difference", which would indicate a two-sided test, which R does by default. [[User:Robinh|Robinh]] ([[User talk:Robinh|talk]])
::: The OP explicitly asked for a one-tailed test. So there's room in this discussion for "here is how to do the calculation asked for in the OP" and also for "the calculation asked for in the OP is problematic and here are some resources for finding a better calculation to do," but there shouldn't be a place for "here is a different calculation from the one asked for in the OP that also is problematic." --[[User:Joel B. Lewis|JBL]] ([[User_talk:Joel_B._Lewis|talk]]) 15:41, 22 July 2018 (UTC)
