First, we need to arrange the numbers in ascending order:

{5, 5.5, 5.5, 6, 6, 6, 6.5, 7, 9}

The median is the middle number in this list, so we need to find the middle number. Since there are 9 numbers in the list, the middle number is the 5th number (counting from the left or the right).

So the median is 6.20 hours (the 5th number in the ordered list).

Therefore, the correct answer is C) 6.20 hours.
