/sci/... I'm struggling with this GRE question. The odd primes I got were 1,3,5,7,11

However the standard dev was 3.8 not 3.71 as suggested.

The answer is E in the back of the book...

Can anyone explain?

>>7409080
>1,3,5,7,11
1 is not a prime, the first five odd prime numbers are 3,5,7,11,13. And remember to not use the sample standard deviation, but the population standard deviation.

Terrible thread. Please sage if you respond to leave room for better threads up top.
