Answer 10

I figured it out

Q3 is the middle term in the second half of an ordered data set.

Answer 11

For example, if you have the data set 1 2 3 4 5 6 7 8, The second half of the data set would be 5 6 7 8, and the middle number would be (6 + 7)/2 or 6.5

Answer 12

In this case, we have the ordered data set 4 6 8 8 8 9 13 15, and the second half is 8 9 13 15. Therefore Q3 = (9 + 13)/2 = 22/2 = 11. So Q3 = 11
