Find the mean speed of Data Set B.

Answer 1

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?

Answer 2

no

Answer 3

You can't?

Answer 4

i could

Answer 5

Well then you should to get the answer :)

Answer 6

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 :)

Answer 7

@tana --> I got 1122 for the sum. Did you?

Answer 9

1122 divided by 18 = 62.3 or 62 1/3
