To examine the effect of pets and friends in stressful situations, researchers recruited 45 women who said they were dog lovers. Fifteen women were assigned at random to each of three groups: to do a stressful task (1) alone, (2) with a good friend present, or (3) with their dogs present.

Which is best at reducing stress?
If you are a dog lover, having your dog with you may reduce your stress level.
Does having a friend with you reduce stress? To examine the effect of pets and
friends in stressful situations, researchers recruited 45 women who said they
were dog lovers. Fifteen women were assigned at random to each of three
groups: to do a stressful task (1) alone, (2) with a good friend present, or (3)
with their dogs present. The stressful task was to count backward by 13s or
17s. The woman's average heart rate during the task was one measure of the
effect of stress. The following table shows the data.
1. Identify any outliers in the three
groups. Show your work.
2. Make parallel boxplots to compare
the heart rates of the women in
the three groups.
