Please please please help! I know how to do this but I can't figure out the answers. Btw you don't have to draw the stem and leaf plot, just help with answers.

Create a steam-and-leaf plot (remember, don't actually do that) for the following set of scores. Then find out the median and the first and third quartiles.

15, 26, 26, 27, 28, 29, 29, 30, 32, 33, 35, 36, 38, 38, 38, 38, 40, 41, 42, 43, 45, 45, 46, 47, 47, 48, 50, 52, 54, 55, 57, 58
