Explanation / Answer

here p=1/3

for n=1332 ; std error =(p**(1-p)/n)1/2 =0.0129

sample proportion phat=504/1332=0.3784

therfore test statistic z=(phat-p)/std error =3.462

for above p value =0.0003 (Note: u have calculated it right but due to rounding of mid level calculation it is coming 0.0003)
