Answer:
The new value for the population mean is 13.
Step-by-step explanation:
Mean:
The mean of a data-set is given by the sum of the values of all observations divided by the number of values, that is:
[tex]M = \frac{s}{n}[/tex]
A set of N= 8 scores has a mean of u = 11.
We find s.
[tex]M = \frac{s}{n}[/tex]
[tex]11 = \frac{s}{8}[/tex]
[tex]s = 11*8 = 88[/tex]
16 points are added to one of the scores
This means that [tex]s = 88 + 16 = 104[/tex]
What is the new value for the population mean?
[tex]M = \frac{104}{8} = 13[/tex]
The new value for the population mean is 13.
