In Evaluating the Following Generalization(s), Identify Sample, Population, Attribute of Interest

question 27

Essay

In evaluating the following generalization(s), identify sample, population, attribute of interest, and the extent to which the claims involved are knowable. Consider carefully the size and diversification of the sample and the extent to which the population differs or may differ from the sample; remember, what's important is that the sample be representative.
Let's say that according to statewide studies done in Montana and Virginia, the infant mortality rate for these two states averaged 10.5 per thousand live births. Could this figure be generalized to the infant mortality rate in the United States? What factors might be relevant to the generalization?
