significance in difference of proportions
Hello,
I'm looking for some guidance with the following problem:
I've 2 samples A (111 items) and B (10 items) drawn from the same unknown
population. Witihn A I find 9 "positives" and in B 0 positives. I'd like to
know if the 2 samples A and B are different, ie is there a way to find out
whether the number of "positives" is significantly different in A and B?
I'm currently using prop.test, but unfortunately some of my data...
