Assuming neither made a mistake in calculations, which of these possible explanations could account for this apparent discrepancy?
I.   One agronomist wrote a one-tailed alternative hypothesis, but the other used 2 tails.
II.  They wrote identical hypotheses, but the one who rejected the null used a higher α-level.
III. They wrote identical hypotheses, but the one who rejected the null used a lower α-level.
