Does alcohol intake affect the probability of kidney disease? For each participant the researcher recorded a lifetime estimate of the number of alcoholic drinks consumed and whether or not the patient was diagnosed with a disease of the kidneys. The researchers want to be able to predict the probability of kidney disease given a number of alcoholic drinks. What statistical test/analysis should they use? A librarian wants to explore if there is a linear association be- tween the number of pages per book and book weight, and if so, use this relationship to predict the weight of books on shelves. What test should they use? Is the Rh blood type associated with the the ABO blood type? Researchers blood typed thousands of randomly sampled individuals. For each person they scored Rh type (+ or -), and ABO type (A, B, AB, or O). What test would you use to see if knowledge of the Rh type help you predict the ABO type?
