Find the mean of first 14 prime numbers.

First 14 prime numbers are = 2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31, 37, 41, 43

Mean = \(\frac{ sum \; of \;  observations }{ number \; of \; observations }\)

Mean = \(\frac{ 2 + 3 + 5 + 7 + 11 + 13 + 17 + 19 + 23 + 29 + 31 + 37 + 41 + 43 }{ 14 }\)

Mean = \(\frac{ 281 }{ 14 }\)

Mean = 20.07
