One Tail or Two Tail Test?

not absolute numbers pls. think in terms of statistical significance - which means beyond plain numbers as you remember. and keep this “testing” for after the 6th. take a chill pill, accept and move on!

Sure cpk, I’ll tell women on June 6th that them earning $34,980 while men earn $41,280 is not really significant…we are all equal.

why 1.65 for t critical not 1.96
