Hi
I am now studying for my final which is tomorrow and i am doing some reviews

how do i do this problem

compute the test statistic used to test the null hypothesis that p1=p2
a report on the nightly news broadcast stated that 13 out of 111 households with pet dogs were burglarized and 23 out of 190 without pet dogs were burglarized.

this question i don't know where to begin, if anyone can help.
