What design? Analyze the design of each researchexample reported. Is it a sample survey, an observational study, or an experiment? If a sample, what are the popula-tion, the parameter of interest, and the sampling procedure? If an observational study, was it retrospective or prospective? If an experiment, describe the factors, treatments, randomi-zation, response variable, and any blocking, matching, or blinding that may be present. In each, what kind of conclu-sions can be reached? 1. Researchers identified 242 children in the Cleveland areawho had been born prematurely (at about 29 weeks).They examined these children at age 8 and again at age20, comparing them to another group of 233 childrennot born prematurely. Their report, published in the New England Journal of Medicine, said the “preemies” en-gaged in significantly less risky behavior than the others.Differences showed up in the use of alcohol and mari-juana, conviction of crimes, and teenage pregnancy.
