Exercise:
Two disease prevention protocols (A, B) for a certain disease were evaluated (infection vs. no-infection). The protocol A (18 cases) showed 14 infection and 4 non-infection cases, whereas the protocol B (22 cases) showed 8 infection and 14 non-infection cases.
Analyze whether there is a statistical difference between protocols A and B in disease prevention.
