Question

Find the mean of first ten prime numbers

Answer 1

First ten prime no 's = 2,3,5,7,11,13,17,19,23,29
Total number of observations = 10
Mean = Sum of all Observations / Total number of Observations
= 2 + 3 + 5 + 7 + 11 + 13 + 17 + 19 + 23 + 29
10
= 129 / 10 = 12.9 

Answer 2

THE 1ST 10 PRIME MEMBERS ARE :
2,3,5,7,11,13,17,19,23,29
SO,
MEAN= (2+3+5+7+11+13+17+19+23+29)/10
           =129/10
           =12.9
