Question

What is the mean of, 50, 30, 40, 10, 20, 80, 60, 90, 10, 30, 110, 70?

Answer 1

Given:

$50,30,40,10,20,80,60,90,10,30,110,70.$

To find:

The mean

Explanation:

The formula for mean is,

$Mean=\frac{Sum\text{ of the observations}}{Total\text{ number of observations}}$

On substitution we get,

$\begin{gathered} Mean=\frac{50+30+40+10+20+80+60+90+10+30+110+70}{12} \\ =\frac{600}{12} \\ =50 \end{gathered}$

Thus, the mean is 50.

Final answer:

The mean is 50.
