Question
Harvard Pilgrim, an insurance company, has reimbursed Cooley Dickinson
Hospital for a large number of health services. It appears that overpayments may have
occurred on many of the reimbursements due to errors in the billing process, or billing for
a more expensive procedure than was actually performed. Cooley Dickinson claims that no
more than 1% of the reimbursements it has received have been overpayments. Harvard
Pilgrim suspects that it is being overcharged and wants to get its money back; so they hire
you to prove their claim. You audit a random sample of 500 reimbursements and find that
20 of them involve overpayments. Perform an appropriate hypothesis test.
