Extracted text: #26 Health Care: Office Visits What is the age distribution of patients who make office visits to a doctor or nurse? The following table is based on information taken a section of the Statistical Abstract of the United States (116th edition). Under 15 20% 65 and older 25% 15-24 25-44 25% 45-64 20% Age group, years Percent of office visitors 10% Suppose you are a district manager of a health management organization (HMO) that is monitoring the office of a local doctor or nurse. This morning the office you are monitoring has eight office visits on the schedule. What is the probability that (a) At least half the patients are under 15 years of age? First, explain how this can be model as a binomial distribution with 8 trials, where success is visitor age under 15 years old and the probability is 20%. (b) From 2 to 5 patients are 65 years old or older (include 2 and 5)? (c) From 2 to 5 patients are 45 years old or older (include 2 and 5)? Hint: Success is 45 or older. Use the table to compute the probability of success on a single trial. (d) All the patients are under 25 years of ag? (e) All the patients are 15 years old or older?
