Hi there. In order to find mean you need to add up all of the numbers and then divide it by the amount of numbers there are. Can you do that?

Well then you should to get the answer :)

53 + 55 + 55 + 55 + 57 + 57 + 60 + 60 + 62 + 63 + 63 + 64 + 67 + 68 + 68 + 70 + 72 + 73 = ?

And there are 18 numbers so you'll divide the sum of the numbers up there^ by 18 and you'll have the mean :)

directrix · Answer

1122 divided by 18 = 62.3 or 62 1/3
