Thewhat is the difference between the mean and median of the first four prime numbers that are more than 4? The mean=9 and the median =11.so the ans should be -2.but in the answer sheet the ans is 0..how?

Mean=9 Median=11 Is it right? Then the difference between them is -2. But here in the answer sheet the ans is 0!!im really confused
