The United States Office of Personnel Management (OPM) manages the civil service of the federal government. Results from its annual Federal Employee Viewpoint Survey (FEVS) are used to measure employee satisfaction on several work aspects, including Job Satisfaction, Pay Satisfaction, Organization Satisfaction, and an overall measure of satisfaction referred to as Global Satisfaction. In each case a 100-point scale with higher values indicating greater satisfaction is used (OPM website, July 6, 2016). Scores for Global Satisfaction, Job Satisfaction, Pay Satisfaction, and Organization Satisfaction for a sample of 65 employees are provided in the DATAfile named Satisfaction.
a. Develop the estimated multiple regression equation that can be used to predict the Global Satisfaction score using the Job Satisfaction, Pay Satisfaction, and Organization Satisfaction scores.
b. Predict the overall Global Satisfaction score for an employee with a Job Satisfaction score of 72, a Pay Satisfaction score of 54, and an Organization Satisfaction score of 53.
