The data from two random samples of 100 students regarding what pet they own is given below
Sample 1
Dog Cat. Bird. Total
54. 38. 8. 100
Sample 2
Dog. Cat. Bird. Total
39. 49. 12. 100
Based on the two samples , what percentage of students own a bird as a pet ?
In sample 1, 8 out of 100 students own a bird as a pet, which is 8%.
In sample 2, 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 take the average of these two percentages.
(8% + 12%) / 2 = 20% / 2 = 10%
Therefore, approximately 10% of students from the two samples combined own a bird as a pet.
