Post Thu Feb 09, 2017 12:20 am
Hi

Can someone please provide better explanation for OG question 150?

Question -
A certain characteristic in a large population has a distribution that is symmetric about the mean m. If 68% of distribution lies within one standard deviation d of the mean, what % of the standard deviation is less than m+d?

Choices -
16%, 32%, 48%, 84%, 92%

Thanks
