Let Ho be the null hypothesis
and H1 be the alternate hypothesis
Let Ho=70%  
Thus, H1≠70%    
σ = sqrt[ P * ( 1 - P ) / n ] 
Sigma 0.01271  
z = (p - P) / σ   
Z-value -1.57359 =(0.68-0.7)/0.01271
P-value 0.115582  
Since the P-value (0.1155) is greater than the significance level (0.02), we cannot reject the null hypothesis.
Ping in case if any confusion
