What is the age distribution of patients who make office visits to a doctor or nurse? The following table is based on information taken from a medical journal. Age group, years Under 15 15-24 25-44 45-64 65 and older Percent of office visitors 15% 5% 25% 15% 40% Suppose you are a district manager of a health management organization (HMO) that is monitoring the office of a local doctor or nurse in general family practice. This morning the office you are monitoring has eight office visits on the schedule. What is the probability of the following? From 2 to 5 patients are 45 years old or older (include 2 and 5). (Hint: Success if 45 or older. Use the table to compute the probability of success on a single trial. Round your answer to three decimal places.)
