Find the mean of the first ten even natural numbers.

Solution:

We have to find the mean of the first ten even natural numbers.

Natural numbers are a part of the number system, including all the positive integers from 1 to infinity.

Given, the data is first ten even natural numbers.

First ten even natural numbers = 2, 4, 6, 8, 10, 12, 14, 16, 18, 20

We know, mean = sum of all observations / number of observations

Sum of observations = 2 + 4 + 6 + 8 + 10 + 12 + 14 + 16 + 18 + 20

= 30 + 30 + 30 + 20

= 110

Number of observations = 10

Mean = 110/10

= 11

Therefore, the required mean is 11.
