8. DeGroot&Shervish (2002) consider an experiment to study the combined effects of taking a stimulant and a tranquilizer. In this experiment three types of stimulant and four types of tranquilizer are administered to a group of rabbits. Each rabbit received one of the stimulants, then 20 minutes later, one of the tranquilizers. One hour later their response time (in microseconds) to a stimulus was measured. The results were: Tranquilizer Stimulant 1...

A counseling psychologist is interested in three types of therapy for modifying snake phobia. However, she does not believe that one type of therapy is necessarily best for everyone; instead, the best type might depend on the severity of the phobia. Undergraduate students enrolled in an introductory psychology course who volunteer are given the Fear Schedule Survey (FSS) to screen out those who show no fear of snakes. Those displaying some fear are classified as either mildly, moderately, or severely...
