I got around 61.416 by adding all of the numbers together then dividing by 12 because that's how many numbers there were.

the mean (average) can be found by adding up all the numbers, then dividing that by how may numbers there are...

(49+50+53+54+55+60+62+68+70+71+72+73) /12 = 737/12 = 61.41..or 61 5/12
