A small difference between means may not be statistically significant, but it could reach statistical significance with a large sample becausea) As N increases, the standard error gets smaller, reflecting less variability in sample means, which allows greater sensitivity to detect small but significant differences. b) As N increases, distributions get more heterogeneous, allowing small differences to be detected. c) The overlap between distributions grows as sample size increases. d) The difference between means gets larger as sample size increases
