13. Consider the following scenario. A health care organization has hired you to do a marketing study regarding new doctors' incomes in your region for the following year. Your data indicates that 100,000 new doctors will be entering your regional market in the next year, and that each will become either an oncologist or a general practitioner. Your income projections for members of each group are as indicated in the following gure: Income per Doctor (in $10005lyear) 150 100 Doctors' Incomes by Specialty, as a Function of the Number of New Oncologists Oncologists General Practitioners 40 60 BO 100 Doctors Becoming Oncologists (in 10005) Imagine that a given doctor believed that 90% of his or her peers were going to become oncologists. If he or she had your study in hand, What would you predict that he or she would choose? (Assume that the doctor cares only about maximizing income.) A. He or she would become a general practitioner B. He or she would not be able to compare the options C. He or she would be indifferent to becoming an oncologist or a GP D. He or she would become an oncologist E. It is impossible to predict this, given the data
