A kennel association compared seven common dog breeds. Each breed is listed with its average lifespan (in years) and is rated in five categories: exercise needs, friendliness, trainability, grooming effort, and food cost.
| Breed | Lifespan (years) | Exercise Needs | Friendliness | Trainability | Grooming Effort | Food Cost |
| Labrador Retriever | 13 | high | very high | high | medium | high |
| German Shepherd | 12 | very high | high | very high | medium | very high |
| Bulldog | 9 | low | high | medium | high | high |
| Poodle | 14 | medium | high | very high | very high | medium |
| Beagle | 13 | high | very high | medium | low | medium |
| Great Dane | 8 | high | medium | low | medium | very high |
| Shih Tzu | 15 | low | high | medium | very high | low |
For each of the following statements, select
Yes if the statement accurately reflects the information provided. Otherwise, select
No.
• Each of the breeds with a lifespan greater than 12 years is rated either very high for grooming effort or very high for friendliness. The breeds with lifespans greater than 12 are Labrador, Beagle, Poodle, and Shih Tzu. Labrador and Beagle are both rated very high for friendliness, while Poodle and Shih Tzu are both rated very high for grooming effort. Since all four breeds meet at least one part of the “or” condition, the statement is correct.
Answer:
Yes • At least one breed with very high trainability also has below-median lifespan. The breeds with very high trainability are German Shepherd and Poodle. The median lifespan among all seven breeds is 13 years. German Shepherd has a lifespan of 12 years, which is below the median. Poodle has 14 years, which is above. Because at least one breed with very high trainability (German Shepherd) is below the median lifespan, the condition is satisfied.
Answer:
Yes • No breed that has high exercise needs is rated low in grooming effort. The breeds with high exercise needs are Labrador, Beagle, and Great Dane. Labrador has medium grooming effort, Great Dane has medium grooming effort, but Beagle has low grooming effort. The presence of Beagle disproves the statement, since it pairs high exercise with low grooming.
