Answer :

mean=average
To find mean, you have to add all the numbers and divide by the number of numbers.

So, 7+3+4+6+9+2+3+5+3=42

42 divided by 9= 4.67

In order to find the mean, you add up all of the numbers and then divide the sum by how many numbers there are, in this case, 9. So, the numbers adds up to 42. You then divide 42 by 9, which is 4.6.....(repeating) 7.
