The article "Strategic Management in Engineering Organizations" (P. Chinowsky, Journal of Management in Engineering, 2001:60-68) presents results of a survey on management styles that was administered both to private construction firms and to public agencies. Out of a total of 400 private firms contacted, 133 responded by completing the survey, while out of a total of 100 public agencies contacted, 50 responded. Can you conclude that the response rate differs between private firms and public agencies?
