The median of the first ten prime numbers is
Answer
Correct Answer : a ) 12.0
Explanation :We know that,
First few prime numbers are 2, 3, 5, 7, 11, 13, 17, ....
Median (if number of observations are even) = ((n/2)th + (n/2 + 1)th) observation/ 2
Median of first ten prime numbers = ((10/2)th + (10/2 + 1)th) prime number/ 2
Median of first ten prime numbers = (5th + 6th prime number)/ 2
Median of first ten prime number = (11 + 13) / 2
The median of first ten prime numbers is 12.
Hence, (a) is the correct answer.
