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.

the answer is -0.102
