It is usually explained in biostatistics textbooks that to do a z-test for the difference of two proportions, it is necessary that p*n and (1-p)*n are both equal to or above five for both samples. However, I did not find any explanation of what to do when this condition is not met?

So I have this table below, and I need to test if there is a significant difference in fuzzy drinks consumption between genders. As you can see, there are only 4 females in the non-consumption category, so the condition for z-testing is not met. What should I do?

Consumption of fuzzy drinks by gender
