Ratbp {PASWR} | R Documentation |
Twelve rats were chosen, and a drug was administered to six rats,
the treatment group, chosen at random. The other six
rats, the control group, received a placebo. The drops in blood pressure
(mmHg) for the treatment group (with probability distribution F) and the
control group (with probability distribution G) are stored in the
variables Treat
and Cont
, respectively. Data are
used in Example 10.18.
