Solution :
This is the RIGHT tailed test .
The null and alternative hypothesis is
H0 : p =0.34
Ha : p >0.34
= x / n = 136/339=0.401
P0 = 0.34
1 - P0 = 0.66
Test statistic = z
= - P0 / [P0 * (1 - P0 ) / n]
= 2.3779 GIVEN IN QUESTION
P(z >2.3779 ) = 1 - P(z < 2.3779) = 1-0.9913=0.0087
P-value =0.0087
