added to the sample, then what is the value of the new population mean



Answer :

MrRoyal

The new population mean is 13

How to determine the value of the new population mean?

The given parameters are:

n = 5 and mean = 12

The mean is calculated as:

Mean = Sum/Count

So, we have

12 = Sum/5

This gives

Sum = 60

When n = 6, and the additional score is 18, we have

Mean = (Initial sum + x)/6

This gives

Mean = (60 + 18)/6

Evaluate

Mean = 13

Hence, the new population mean is 13
