Question: In its Audit of Computerized Criminal History the Florida Department
In its Audit of Computerized Criminal History, the Florida Department of Law Enforcement (FDLE) periodically reviews the accuracy and completeness of its criminal history database. The database contains thousands of records. The FBI/Bureau of Justice Quality Standards require that at least 95% of all records in the state’s database be complete and accurate. The audit uses a simple random sample to determine whether the state has met the standard. In a recent FDLE audit, the auditor found that only 555 records of the 605 records sampled were perfectly complete and accurate; the others were either incomplete or contained at least one error (source: fdle.state.fl.us/publications/). Is this sample evidence sufficient to reject, at the 5% significance level, a null hypothesis that the population of Florida criminal records meets FBI/ Bureau of Justice Quality Standards? Explain.
