Question:

In 1990, 5.8% of job applicants who were tested for drugs failed the test. At the 1% significance level, test the claim that the failure rate is now higher if a random sample of 1520 current job applicants results in 96 failures. Round your proportion estimate to the nearest thousandth. Complete the following problem. Make sure you show the following for each hypothesis test:
(a) H0
(b) H1
(c) The test statistic (round to the nearest thousandth)
(d) The critical value(s)
(e) The P-value (round to the nearest thousandth, use 0+ if necessary)
(f) The conclusion (reject H0 or fail to reject H0)
(g) The final conclusion stated in non-technical terms
Assume all requirements are met to complete each of the hypothesis tests. If a significance level is not given, think about the seriousness of a type I error to determine which level of significance to use?
