The data from two random sample of 100 students regarding what pet they own. Based on Two samples, what percentage of students own a horse as a pet?
Sample 1, 5 students own a horse
Sample 2, 7 students own a horse
A. 5 %
B. 6%
C. 10%
D. 7 %
The total number of students in both samples is 200. Adding the number of students owning a horse in each sample (5+7=12), we find that 12 out of 200 students own a horse.
Therefore, the percentage of students owning a horse as a pet is (12/200) x 100 = 6%.
Therefore, the correct answer is B. 6%.
