A researcher wants to investigate different weigh loss options in rats. He divides 24 rats (equal weights) into 3 groups: Control (do not receive any physical exercise), Exercise (receive 6 weeks of physical exercise), and Pill(take diet pill for 6 weeks). He then measures their weight in grams after the 6 week period. Descriptives Weight 95% Confidence Interval for Mean Mean Std. Deviation Std.
