Answer 5

The median is 28 (There are 18 elements in the data set so it's the value in between 9 and 10 -- Which are both 28)
Then the 1st quartile is the element in the middle of the first half of the data -- The middle of the first 9 elements which is the 5th.
and the 3rd quartile is the 5th element after then median which is 32.
