A manufacturer has received complaints that aging production equipment is forcing workers to work overtime in order to meet production quotas. Historically, the average hours worked per week is 40 with a standard deviation of 7.5 hours. If a sample of 25 workers found that the average work week is 48 hours, conduct a hypothesis test to determine if there is significant evidence that the length of the average work week has increased? Use alpha=.05 (State the Hypothesis Scenario, calculate the test statistics or p - value and state the conclusion)
