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
