We need to find the difference first. 65 - 60 = 5. Now we must find what percent 5 is of 65. It is 7,7%. The number decreased, and so it is a 7,7% decrease.
To find the median, you order the numbers from least to greatest, then find the middle number.
3,7,3,2,7,9
2,3,3,7,7,9
There are two middle numbers, so we have to find the middle of the two.
3,4,5,6,7
5 is the median, so the answer is B.
