Question

13. Calculate the arithmetic mean for first ten odd Natural numbers.

​

Answer 1

Answer:

First ten odd natural numbers are

1 ,3 ,5 ,7 ,9 ,11 ,13 ,15 ,17 ,19 

mean = sum of all the observations / Total number of observations

          = 1 + 3 + 5 + 7 + 9 + 11 + 13 + 15 + 17 + 19 / 10

          = 100 / 10

           = 10

 So the mean is 10

Answer 2

$\huge\mathfrak{Answer:-}$

First ten odd natural number are :-

${\implies}$ ${1,3,5,7,9,11,13,15,17,19}$

${\implies}$ ${Mean=}$ $\frac{Sum Of All Observations}{No Of All Observations}$.

${\implies}$ = $\frac{10</p><p>1+3+5+7+9+11+13+15+17+19}{10}$

${\implies}$ = $\frac{100}{10}$${=10}$.
