Answer 1

To find the median, we need to first put the data in order from least to greatest:

3, 4, 5, 5, 6, 7, 8, 9, 10, 9.5

Now we can determine the middle number(s). Since there are an odd number of data points, the median is simply the middle number:

Median = 6

Therefore, the answer is (A) 6.
