RATBP: Rat Blood Pressure

Description

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), respectively, were recorded.

Usage

RATBP

Format

A data frame with 12 observations on the following 2 variables:

• mmHg (drops in blood pressure in mm of Hg where positive values are decreases, negative values are increases)

• group (factor with levels control and treatment)
