Will there be a time when hiring decisions will be done using a computer algorithm, and without any human involvement? A survey found that 60% of the adults surveyed were worried about the development of algorithms that can evaluate and hire job candidates. To check this claim, a random sample of n = 100 U.S. adults was selected, with 55 saying they were worried about this issue.
(a) Construct a 98% confidence interval for the true proportion of adults that are worried about being "hired by a robot." (Round your answer to three decimal places.)
_______ to _______
We have given,          
   
          
   
x=55          
n=100          
Estimate for sample proportion=   0.55  
Level of significance is =1-0.98=0.02  
   
Z critical value(using Z table)=2.326  
   
          
   
Confidence interval formula is      
       
=(0.434,0.666)
          
   
Lower limit for confidence interval=0.434  
          
   
Upper limit for confidence interval=0.666
