Question 1147799
p hat is 64/458=0.14
alpha is 0.05 (suppose) p{reject Ho|Ho true}
test statistic is z=(phat-po)/sqrt(p*(1-p))/n
this is -0.02/sqrt(0.16*0.84/458)
=-1.18 (not rounding p hat)
fail to reject Ho with p-value of 0.14 (not rounding)
if 0.14 is used for p hat, the values are -1.17 and 0.12
