Given:
First 15 prime numbers
To find:
The mean of these numbers
Solution:
The required value of the mean is 21.8.
We can obtain the mean by adding all the given prime numbers and dividing them by the total numbers given.
The prime numbers given are as follows-
2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31, 37, 41, 43, 47.
The total numbers=15
The sum of the prime numbers=2+3+5+7+11+13+17+19+23+29+31+37+41+43+47
=328
The required mean=Sum/total terms
Using the values, we get
=328/15
=21.8
Therefore, the required value of the mean is 21.8.
