A study released in the this month’s issue of Sports Illustrated magazine reveals that colleges with “bird” mascots have done better than those with animals, fantasy figures, or humans for mascots. Here is how it shapes up
| Mascot | Winning Percentage |
| Birds | 58% |
| Fantasy figures/inanimate objects/weather | 52% |
| Canines and felines | 47.9% |
| Other Beasts | 46.5% |
| People | 41.1% |
According to this study alone which of the following teams should win? What is the difference in the winning percentages for their mascot types?
