(Answered) Question business and management the 40-hour work week did

Statistics

Question: Business and Management The 40-hour work week did not become a U.S. standard until 1940. Today, many white collar employees work more than 40 hours per week because management demands longer hours or offers large monetary incentives. A random sample of white-collar employees was obtained, and the number of hours each worked during the last week are given in the following table.

Is there any evidence the true mean number of hours worked by white-collar employees is greater than 40? Use a = 0.01. What assumption(s) did you make in order to complete this hypothesis test?
