Given:
[tex]50,30,40,10,20,80,60,90,10,30,110,70.[/tex]To find:
The mean
Explanation:
The formula for mean is,
[tex]Mean=\frac{Sum\text{ of the observations}}{Total\text{ number of observations}}[/tex]On substitution we get,
[tex]\begin{gathered} Mean=\frac{50+30+40+10+20+80+60+90+10+30+110+70}{12} \\ =\frac{600}{12} \\ =50 \end{gathered}[/tex]Thus, the mean is 50.
Final answer:
The mean is 50.
