A sample of n=8 scores has a mean of m=12. What is the value of ∑x for this sample

We are given the mean of 8 scores is 12.

We are required to find the sum of these 8 observation's, $\sum x$

We know that:

$\bar{x}=\frac{\sum x}{n}$

We are given:

$\bar{x} = 12, n=8$

$\therefore 12=\frac{\sum x}{8}$

$\sum x = 12 \times 8$

$\sum x=96$

Hence, sum of 8 observation's, $\sum x =96$
