In recent years the average time it takes audit teams from Trimble and Martin to complete a company audit has been 55.8 hours. In monitoring the performance of one of these audit teams recently, reviewers found that the average time for a random sample of team audits differed by nearly 6 hours from the company average. If you were to use the sample average in a hypothesis test to determine if this team’s average performance is different from the overall company average, what null and alternative hypotheses would you recommend?
