To better understand their employee demographics, this organization has hired you to determine a few key pieces of information. Therefore, the organization has randomly selected a sample of five staff, five lower management, and five upper management employees to determine whether these groups differ in terms of their age, years with the company, and years of post-high school education. Additionally, this organization would like to know which of the variables associates with job satisfaction to help inform future interventions. As this organization's statistical consultant, answer the following questions: 1. Focusing only on staff: The known U.S. mean job satisfaction for staff workers is 38. Do the five staff workers in this sample differ from the overall population in terms of their job satisfaction? 2. First, do job levels (staff, lower management, upper management) differ in terms of their years years of post-high school education? Second, do those job levels differ significantly concerning job satisfaction. If significant differences among those groups emerge, use the Bonferroni correction to identify which specific groups differ from each other. Data See next page for data tables
