These data are the annual medical claim costs for the Emerald 
health care providers during the period 1986 - 1992, the
Consumer Price Index (CPI), and the medical portion of the CPI. 
[The CPI is an index compiled by the U.S. government which measures
the cost of a typical U.S. wage-earner's purchased goods and
services. It includes for example the wage-earner's food costs,
transportation costs, health care costs, housing costs, etc.] Use
these data to refute or support Emerald's claim that the cost of
their health plan has risen more slowly than either the CPI or the
medical portion of the CPI.
