If a sample, what are the population, the parameter of interest, and the sampling procedure? If an observational study, was it retrospective or prospective? If an experiment, describe the factors, treatments, randomization, response variable, and any block- ing, matching, or blinding that may be present. In each, what kind of conclusions can be reached?
