Answer:

The answer is B

Step-by-step explanation:

You order them from least to greatest- 16, 17, 19, 24, 28, 30, 31, 32, 36, 37, 40, 43, 45.

Then you find the middle number or the median- 31

Then you go to the left of the medain and get the first quartile- 19, 24 (You have to find the mean of these two numbers- 21.5)

Then you go to the right of the medain and get the third quartile- 37, 40 (Again you must find the mean of these two numbers- 38.5)

Last you would put them in the order needed.

Hope this helps! :)
