Answer 1

Question : -

Find the mean of first 12 Natural numbers!

Answer : -

First 12 Natural numbers are : -

1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12 .

Formula of mean

For ungrouped data : -

$= > \: \frac{sum \: of \: all \: observations}{number \: of \: observations}$

$= > \: \frac{1 + 2 + 3 + 4 + 5 + 6 + 7 + 8 + 9 + 10 + 11 + 12}{12}$

$= > \frac{78}{12}$

$= > 6.5$

* Mean of first 12 Natural numbers is 6.5

Answer 2

Answer:

First 12 natural numbers are: 1,2,3,4,5,6…. ... Now, substitute 78 for the sum of observations and 12 for the total number of observations in the formula M=Sn to determine the arithmetic mean. M=Sn=7812=6.5. Hence, 6.5 is the arithmetic mean of the first 12 natural numbers.
