• A. 5.6
• B. 5
• C. 4.8
• D. 4

Answer 1

The correct option is B

5

We know that,
The mean or mean value of a given number of observations is simply its average value.
i.e. sum of values of all the observations divided by the total number of observations.

$\text{Mean}$ = $\frac{Sumofobservations}{Numberofobservations}$

Now mean,
$=\frac{2+6+4+9+7+3+5+4+3+7}{10}$
$=\frac{50}{10}$
$=5$

Thus, the mean of the given numbers is 5.
