A researcher wants to test the hypothesis that increasing
temperature and physical exercise increases the body’s skin
conductivity (as measured by a galvanometer). A sample of 24 males,
all 21 years old is randomly selected, and the subjects are
randomly assigned to four treatment conditions. Group A is
subjected to high temperature and physical exercise (jogging in
place for 10 minutes). Their GSR (Galvanic skin response) scores in
decivolts are 9, 8, 8, 10, 7, and 8. Group B is...
