A certain HMO is attempting to show the benefits of managed care to an insurance company. The HMO believes that certain types of doctors are more cost-effective than others. One theory is that certification level is an important factor in measuring the cost-effectiveness of physicians. To investigate this, the HMO obtained independent random samples of 30 physicians from each of the three certification levels- Board certified (C); Uncertified, board eligible (E); and Uncertified, board ineligible (I)- and recorded the total per-member, per-month charges for each (a total of 90 physicians). Identify the dependent (response) variable for this study.
A) the HMO
B) the three certifications groups- C, E, and I
C) the 90 physicians
