Answer 1

To find the mean life span of the farm animals, we first need to add up all the life spans and then divide by the number of animals.

The life spans are:
- Chicken: 7 years
- Duck: 10 years
- Horse: 22 years
- Pig: 10 years
- Sheep: 12 years
- Cow: 10 years
- Goat: 12 years

Now, let’s add these together:

7 + 10 + 22 + 10 + 12 + 10 + 12 = 93 years

Next, we count the number of animals:

There are 7 animals.

Now, we divide the total life span by the number of animals to find the mean:

Mean = Total Life Span / Number of Animals
Mean = 93 / 7 ≈ 13.29 years

Thus, none of the provided responses (10 years, 11.9 years, 12 years, 15 years) are correct as the mean life span is approximately 13.29 years.
