Suppose a public health official wants to estimate the true proportion of Wisconsin residents who were diagnosed with
influenza in the last year. The public health official randomly selects 2000 medical records of people who visited their doctor
in the last year. She records whether a diagnosis of influenza appears in the medical record. The public health official then
computes the proportion of people diagnosed with influenza among these 2000 individuals.
