An Egg Production Company recently found that eating eggs does not increase a person’s blood serum cholesterol. Five hundred subjects participated in a study that lasted for 2 years. The participants were randomly assigned to either no-egg group or a moderate-egg group. The blood serum cholesterol levels were checked at the beginning and end of the study. Overall, the groups’ levels were significantly different. The company reminds that eating egg is healthy if done in moderation. Many of the previous studies relating eggs and high blood serum cholesterol jumped to improper conclusion. Using this information, answer the following questions: What prompted the study? What is the population under study? Was a sample collected?
