4. If you are a dog lover, perhaps having your dog along reduces the effect of stress. To examine the effect of pets in stressful situations, researchers recruited 48 women who said they were dog lovers. Sixteen of the subjects were randomly assigned to each of three groups to do a stressful task-alone (the control group C), with a good friend present (F), or with their dog present (P). The subject's average heart rate during the task is one measure of the effect of stress. The following is the output from ANOVA run on crunch-it. . Based on the screenshot of analysis, please record the information listed below in your answer, and then draw your conclusion. Be sure to decide if this was appropriate to run in the first place. Write a one or two sentence summary in non-statistical language to describe what you have found, not how you found it. Your audience is people who have never had a statistics class (think of middle of the road 8th graders, not the really bright ones).
