Question

The Data set shows the ages of the members of two clubs.

CLUB A: 42, 38, 40, 34, 37, 46, 38, 45
CLUB B: 30, 44, 42, 61, 24, 27, 59, 65 m
(10 Points)
Find the mean age for CLUB A :

Answer 1

it goes by +4 and -4

Explanation:

Answer 2

Answer: 40

You can find the mean for club A by adding up every number in the set and then dividing by the amount of numbers in the data set:

So first we add up 42+38+40+34+37+46+38+45
Which = 320

Now we divide that number by 8 because there are 8 numbers in the data set (all the numbers we added up):

320/8=40

So now we know that the mean age is 40!

Hope this helps :)!
