Carbon Monoxide Transfer

SUMMARY:
       The co.transfer data frame  has  7  rows  and  2  columns.
       Seven  smokers  with chickenpox had their levels of carbon
       monoxide transfer measured on entry to hospital  and  then
       again  after  1 week.  The main question being whether one
       week of hospitalization  has changed the  carbon  monoxide
       transfer factor.

DATA DESCRIPTION:
       This data frame contains the following columns:

entry:    Carbon monoxide transfer factor on entry to hospital.
week:     Carbon monoxide transfer one week after  admittance  to
       hospital.
