As seen in the question, I think that it should be a 2sample t test, but I would just like to make sure my thinking is on the right path. I considered Chi squared : The sample size doesn't exactly matter here, but because the "before" and "after" matters, and especially with 2 methods A and B, it sounds plausible to draw a contingency table. However, this doesn't offer a Yes/No option, thus we cannot use a chi squared test. 2 sample ttest is selected because sample is small, < 30, and we can simply compare method A with method B here.
