CASE STUDY Cats or dogs—which is the better pet for relieving stress? To answer this age-old question, your DSC decided to test whether they should start a “Furry Friends” program for emotional support during exams using dogs or cats. To test the difference, they selected 40 random people who didn’t have a pet at home. Each person was randomly assigned to either a cat treatment or a dog treatment and asked to drop by the test room for 30 min...

3. Let G be a group containing 6 elements a, b, c, d, e, and f. Under the group operation called the multiplication, we know that ad = c, bd = f, and f2 = bc = e. We showed you in class that the identity is e, hence the e-row and e-column were revealed. Using associativity, we also found cb, cf, af, and a2. Now try to imitate the idea and find five more entries. Justify your answer. Hint:...
