Answer 1

To calculate the percentage of students who have dogs for pets, we divide the number of students with dogs (10) by the total number of students (10+8+2+3=23), then multiply by 100:

(10/23) * 100 = 43.5%

To calculate the percentage of students who have hamsters for pets, we divide the number of students with hamsters (3) by the total number of students (23), then multiply by 100:

(3/23) * 100 = 13%

Therefore, the difference in percentage of students who have dogs for pets and the percentage of students who have hamsters for pets is:

43.5% - 13% = 30.5%

Therefore, the correct answer is A. The difference in the percentage of students who have dogs for pets and the percentage of students who have hamsters for pets is 30.4%.
