Answer 1

Here your answer goes ..........

$\leq Step :- 1 \geq$

The  formula of Mean for Ungrouped data as below :-

$\frac{Sum}{Totalno.}$ of observation

$\leq Step :-2 \geq$

First five positive integers are

1 , 2 , 3 , 4 , 5

$\leq Step :- 3 \geq$

Today Observation :- 5

Sum  of all observation :- 1 + 2 + 3 + 4 + 5

Put the value in the formula :-

$\frac{1+2+3+4+5}{5}$

===> $\frac{15}{5}$

===> 3

Therefore ,  the mean of the first five positive integers is 3

Answer 2

$\huge \bold {\mathfrak {hey}}$

$\underline \bold { First \: 5 \: Positive \: Integers}$

➡️ $\bold { 1,2,3,4,5}$

✔️ Formula To Find Mean

Sum of total number observations
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ =?
Total number of observations

Now,

We know,

Total number of observations = 5
Sum of number of observations = 1+2+3+4 + 5

Put these in formula

1 + 2 + 3 + 4 + 5
~~~~~~~~~~~~~~ =
5

➡️ 15 / 5

We know if we multiply ✖ 5 × 3 we get 15

Therefore, the 15 will be cut by 5 on 3.

So the mean should be 3.
