Should male managers wear a tie during the workday to command respect and demonstrate professionalism? Suppose a measurement scale has been developed that generates a management professionalism score. A random sample of managers in a high-tech industry is selected for the study, some of whom wear ties at work and others of whom do not. One subordinate is selected randomly from each manager’s department and asked to complete the scale on their boss’s professionalism. Analyze the data taken from these independent groups to determine whether the managers with ties received significantly higher professionalism scores. Let α = .05.
