Answer #1

We have given,          
          
x=27      
n=52      
Estimate for sample proportion=   0.51923
Z critical value(using Z table)=2.58  
Confidence interval formula is  



=>(0.340,0.698)
          
Lower limit for confidence interval=0.340
          
Upper limit for confidence interval=0.698
