Answer #1

We have given,              
              
x=153          
n=2924          
Estimate for sample proportion
Level of significance is =1-0.99=0.01      
Z critical value(using Z table)=2.58  
  
Confidence interval formula is              


=(0.042,0.063)              
Lower limit for confidence interval=0.042
              
Upper limit for confidence interval=0.063

We are 99% confident that population proportion  of adverse reactions is between 0.042 to 0.063
