Assembly workers at Coastal Computers Inc. assemble just one or two subassemblies and insert them in a frame. The executives at CC think that the employees would have more pride in their work if they assembled all of the subassemblies and tested the complete computer. A sample of 28 employees was selected to experiment with the idea. After a training program, each was asked his or her preference. Nineteen liked assembling the entire unit and testing it. At the 0.050 level, can we conclude the employees preferred assembling the entire unit?
