Hypothesis testing-drug testing of job applicants

Reference no: EM13111689

Drug testing of job applicants - In 1990, 5.8% of job applicants who were tested for drugs failed the test. At the 0.01 significance level, test the claim that the failure rate is now lower if a simple random sample of 1520 current job applicants results in 58 failures. Does this result suggest that fewer job applicants now use drugs?
