Explanation / Answer

here p=0.48

and n=430

hence std error =(p(1-p)/n)1/2 =0.024

hence test stat z=(phat-p)/std error =(0.47-0.48)/0.024=-0.42

and corresponding p value =0.3385

C Do not reject Ho. There is insufficient evidence that the probability of selecting a household with no children is not equal to the value obtained by the census
