Solution

Formulating the hypotheses          
Ho: p1 - p2   <=   0  
Ha: p1 - p2   >   0  
Here, we see that pdo =    0   , the hypothesized population proportion difference.  
          
Getting p1^ and p2^,          
          
p1^ = x1/n1 =    0.45      
p2 = x2/n2 =    0.34      
          
Also, the standard error of the difference is          
          
sd = sqrt[ p1 (1 - p1) / n1 + p2 (1 - p2) / n2] =    0.09280625      
          
Thus,          
          
z = [p1 - p2 - pdo]/sd =    1.185265004 = 1.19 [ANSWER, TEST STATISTIC]

Also, the p value is, as this is right tailed,          
          
P =    0.117956343 = 0.1180 [ANSWER]
