WebInterestingly, combining the two brings about a significant p -value in the Fisher test: p = 0.0175. This is weird because I could have chosen the exact opposite test ( μ > 0) and sampled results - and still get p = 0.0175. It's almost as if the Fisher test does not take the direction of the hypothesis into account. Can anyone explain this?
