# Is is statistically correct to use binom.dist in excel to test equality of two population proportions?

I have two independent populations with size n1=272 and n2=664. The number of successes are x1=4 and x2=6 respectively.

Is it statistically correct to use binom.dist() function to test the equality of two population proportions? In particular, can I obtain the p-value of the hypothesis test as follows:

binom.dist(6,664,4/272,TRUE)


or in general,

binom.dist(x2,n2,x1/n1,TRUE)

• When you write "to test the two population proportions", you ought to clarify what is the actual hypothesis you wish to test. When you say you have two "populations" with size n1=272 and n2=664, are these actually the whole populations, or are they merely samples from those populations? – Silverfish Aug 30 '16 at 10:15
