To investigate if there is an association between eating red meat and the health of individuals, researchers used data from a national survey of 120,000 randomly selected American adults. In the data, there was a strong association between the amount of red meat consumed and the frequency and severity of illnesses contracted.
(a) Is this an experiment or an observational study? Explain.
(b) Is it legitimate to deduce that the observed association in the data generalizes to all American adults? If yes, explain why. If not, explain why not.
(c) Is it legitimate to deduce from this study that eating red meat caused the subjects in the study to be more prone to illness? If it is, explain carefully. If not, identify a possible confounding variable explaining carefully why your variable is confounding.
