Question

Nikita se the mean of prime numbers between 10 and 20 is 12 do you agree give reason ​

Answer 1

I am not agree because the mean of prime numbers between 10 and 20 is 15.

Step-by-step explanation:

Given,

Nikita say the mean of prime numbers between 10 and 20 = 12

The prime numbers between 10 and 20 are:

11, 13, 17 and 19

Here, number of observations = 4

We know that,

Mean $=\dfrac{The sum of all observations}{Number of observations}$

$=\dfrac{11+13+17+19}{4}$

$=\dfrac{60}{4}=15$

The mean of prime numbers between 10 and 20 = 15

Hence, i am not agree because the mean of prime numbers between 10 and 20 is 15.
