The Bureau of Finance has always been a relaxed place to work. Employees are allowed 60 minutes for a lunch break and are not required to sign or punch in or out. Recently the head of the Bureau has come to suspect employees are taking advantage of the comfortable atmosphere by disappearing for more than 60 minutes at lunch. He decides to check his suspicions by monitoring for a week the number of minutes spent at lunch by each employee in a typical department of the Bureau. He considers a lunch break of up to 65 minutes acceptable, longer than that unacceptable. Below are the data collected. Should the head of the Bureau be concerned about the time taken at lunch by employees? Present the data in ways to support your answer.
