If you plan to perform m = 10 pairwise tests and want to keep familywise alpha = 0.05, what Bonferroni-adjusted per-comparison alpha should you use? If a particular unadjusted p = 0.004, does it survive the correction?

Adjusted α' = 0.05; significance is unchanged so p = 0.004 is significant but adjustment is unnecessary.

Adjusted α' = 0.005; yes, p = 0.004 is significant after Bonferroni (p_adj = 0.04 < 0.05).

Adjusted α' = 0.01; no, p = 0.004 is not significant because Bonferroni requires multiplying p by the number of groups rather than the number of comparisons.

Adjusted α' = 0.0005; yes, p = 0.004 is still significant because you always use a Bonferroni threshold of 0.001 for scientific studies.
