Question

The mean of $30,32,24,34,26,28,30,35,33,25$ is $29.7$.
If true, then enter $1$ and if false, then enter $0$.

• A. $0$
• B. $1$
• C. None of these
• D. Can not be determined

Answer 1

The correct option is B $1$

Mean of the series: $30,32,24,34,26,28,30,35,33,25$.

We know, Mean is given by,

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

Here, number of observations $=10$.

$⟹$ Mean $=\frac{30+32+24+34+26+28+30+35+33+25}{10}$
$⟹$ Mean = $\frac{297}{10}$ = $29.7$.

That is, the given statement is true.

Therefore, option $B$ is correct.
