Given:
The scores:
3,810, 5,300, 8,560, 4,200, 5,340.
There are 5 scores.
We know that
[tex]\text{Mean}=\frac{The\text{ sum of the all scores}}{The\text{ number of scores}}[/tex][tex]\text{Mean}=\frac{3810+5300+8560+4200+5340}{5}[/tex][tex]\text{Mean}=\frac{27210}{5}=5442[/tex]The mean for the scores is 5,442.
