To find the percentage of students who own a horse as a pet based on the two samples, we need to add up the number of students from both samples who own a horse, and then divide that by the total number of students across both samples.
Total number of students who own a horse = 5 (from Sample 1) + 7 (from Sample 2) = 12
Total number of students in both samples = 100 (from Sample 1) + 100 (from Sample 2) = 200
Percentage of students who own a horse = (12/200) * 100% = 6%
Therefore, based on the two samples, 6% of students own a horse as a pet.
The data from two random sample of 100 students regarding what pet they own is given below.
| | Horse | Dog | Cat | Total
Sample 1 | 5 48 47 100
Sample 2 | 7 61 32 100
