The data from two random samples of 100 students regarding what pet they own is given: simple one: 54 people own a dog, 38 people own a cat, and 8 people own a bird. In sample two 39 people own a dog, 49 people own a cat, and 12 people own a bird.
Based on the two samples, what percentage of students own a bird as a pet?
In sample one, 8 out of 100 students own a bird as a pet, which is 8%.
In sample two, 12 out of 100 students own a bird as a pet, which is 12%.
To find the overall percentage of students who own a bird as a pet, we can calculate the average of these two percentages:
(8% + 12%) / 2 = 10%
Therefore, based on the two samples, 10% of students own a bird as a pet.
