They found that men who had high cholesterol tended to eat an excessive amount of fatty foods. a. Identify the population for the study. b. Identify the sample for the study. c. Was this an observational study or a controlled experiment? Explain how you know. d. Assuming the rest of the study was well-designed, use your answers to discuss whether it would be reasonable to conclude that eating fatty foods caused high cholesterol.
