Fowlkes et al. (J. Am. Statist. Assoc., 83: 611–622, 1988) reported results of a survey of employees of a large national corporation to determine how satisfaction depends on race, gender, age, and regional location. The data are at www.stat.ufl.edu/∼aa/cda/cda.html. Fowlkes et al. reported “The leastsatisfied employees are less than 35 years of age, female, other (race), and work in the Northeast; . . . The most satisfied group is greater than 44 years of age, male, other, and working in the Pacific or Mid-Atlantic regions; the odds of such employees being satisfied are about 3.5 to 1.” Analyze the data, and show how you would make this interpretation.
