Question 923658
As a condition of employment, Fashion Industries applicants must pass a drug test. Fashion Industries randomly tests its employees throughout the year. Last year in the 530 random tests conducted, 20 employees failed the test.
 (1) 
Develop a 95 percent confidence interval for the proportion of employees that fail the test. (Round your answers to 3 decimal places.)
---
p-hat = 20/530 = 0.0377
ME = 1.96*sqrt[0.0377*0.9623/530] = 0.0162
-------
95% CI: 0.0377 - 0.0162 < p < 0.0377+0.0162
