To find the mode of the life spans of the farm animals, we need to identify which life span occurs most frequently in the provided data.
Here are the life spans of the farm animals listed:
- 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 life span:
- 7 years: 1 occurrence (Chicken)
- 10 years: 3 occurrences (Duck, Pig, Cow)
- 12 years: 2 occurrences (Sheep, Goat)
- 22 years: 1 occurrence (Horse)
The life span that appears most frequently is 10 years, which occurs 3 times.
Therefore, the mode of the life spans of the farm animals is 10 years.
