Question

A population of scores has a sum of x = 60 and a mean = 12. how many scores are in this population?

Answer 1

We have: Mean = Total Sum / Total numbers
Here, Mean = 12
Total Sum = 60
Total numbers = N

Substitute their values into the expression:
12 = 60 / N
N = 60 / 12
N = 5

In short, There will be five scores in total. So, Your Final Answer is 5

Hope this helps!
