Question

nikitha said the mean of prime number between 10 and 20 is 12. do you agree? give reason​

Answer 1

Answer:

not I am not agree because the answer is n/2 (n/2+1+n/2)

Answer 2

Hey there,

Prime no between 10 and 20 are

11, 13, 17 and 19

So mean = sum of observations / no of observations

= 11+13+17+19 / 4

= 60 / 4

= 15

So correct mean is 15 not 12

Hope it help
