In 1990, 6.1% 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 1620 current job applicants results in 68 failures (based on data from the American Management Association). Does the result suggest that fewer job applicants now use drugs? Answer all of the following questions. i. Hypothesis Statements ii. Test Type iii. Conditions iv. Level of Significance v. Critical Value vi. Test Statistic vii. p-value
