Question 1193430: HighTech Incorporated randomly tests its employees about company policies. Last year in the 480 random tests conducted, 10 employees failed the test.
a. What is the point estimate of the population proportion that failed the test? (Round your answers to 1 decimal places.)
b. What is the margin of error for a 98% confidence interval estimate? (Round your answers to 3 decimal places.)
You can put this solution on YOUR website! the point estimate p hat=10/480=2.083% or 2.1%
the 98% half-interval, which is the margin of error, is z(0.99)*sqrt(0.0283*0.97917/480)
=2.326*0.00652
=0.0152 or 0.015
