To find the mode of the life spans of the farm animals, we need to identify the lifespan that appears most frequently in the provided data:
- Chicken: 7 years
- Duck: 10 years
- Horse: 22 years
- Pig: 10 years
- Sheep: 12 years
- Cow: 10 years
- Goat: 12 years
Now, let's count the occurrences of each lifespan:
- 7 years: 1 occurrence (Chicken)
- 10 years: 3 occurrences (Duck, Pig, Cow)
- 12 years: 2 occurrences (Sheep, Goat)
- 22 years: 1 occurrence (Horse)
The lifespan that occurs most frequently is 10 years, with 3 occurrences.
Thus, the mode of the life spans of the farm animals is 10 years.
