borderline significantp = 0.08
For the increase from 0.7 to 2.5 doublings/h (which shows the strongest difference), a Wilcoxon test finds a borderline difference between the distribution of major and minor isoacceptors ( p = 0.06), a Welch's t -test on difference in mean ratios is also borderline significant ( p = 0.08), but the bootstrap test on the difference in mean ratios is not significant ( p = 0.10).
