I would like to compare the pass rates of two different classes (say English 111 and English 113). The data is binomial (0= fail, 1=pass). The sets are unequal size. I think its safe to assume independent population means and unknown SD. I am inclined to use Welch's t - test. But I am not sure if it works for binomial data.
If Welch's can't be used with binomial data, can you provide a suggestion?
I did search the forums for information on Welch's t-test, but did not see this question come up.
Thank you in advance.
