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? The radioactive gas radon, found in some homes, poses a health risk to residents. To assess the level of contamina-tion in their area, a county health department wants to test a few homes. If the risk seems high, they will publi-cize the results to emphasize the need for home testing. Officials plan to use the local property tax list to randomlychoose 25 homes from various areas of the county.
