Answer 2

Answer:

=> Mean = $5.6$

Step-by-step explanation:

Here, it is given that:-

For the first $5$ prime numbers,

We have to find the mean.

Prime numbers are those that have only two factors: and the number itself.

The first $5$ prime numbers are $2,3,5,7$ and $11$.

The formula of the mean is

$=\frac{\text { Sum of observations }}{\text { Number of observations }}$

Therefore,

$=> 2+3+5+7+11$

$=> 28$

Now, we will divide this by $5$ as there are a total

$=> \frac{28}{5}$

$=>5.6$

Hence, the required mean is 5.6
