The (hypothetical) data given below are based on a random sample of customers shopping at alocal electronics store. The goal of the study was to determine whether students are equallylikely to own an iPad than non-students. The study was conducted by asking the first 500customers who walked into the store: (1) if they were currently full-time students (yes/no) and(2) if they own an iPad (yes/no). The following data were obtained:Full-time studentOwn an iPadYesNoYes68112No44276(a)probability that a customer owns an iPad?
