To examine the effect of pets in stressful situations, researchers recruited 21 women and 21 men who said they were dog lovers. |
Seven of each gender were randomly assigned to each of three groups to do a stressful task alone (the control group), with a |
good friend present, or with their dog present. The subjects mean heart rate (in beats per minute) during the task is one measure |
of the effect of stress. The data are given below. Analyze these data with the appropriate model of two-way ANOVA. Put your hypotheses |
and your conclusions in the box provided using our standard format. The correct ANOVA table should be put out to the right. |
