T test on ratios

WebPaired vs. ratio t tests. The paired t test analyzes the differences between pairs. For each pair, it calculates the difference. Then it calculates the average difference, the 95% CI of that difference, and a P value testing the null hypothesis that the mean difference is really zero.
