Find the area under the standard normal curve:
I. to the right of z = 0.09
look up using z-score chart: 0.5359
to the right:
1-0.5359 = 0.4641
II. to the left of z = 0.09
to the left is simply: 0.5359

Hi,

Note:  Bell shaped Curve showing placement of z = 0, z = ±1, 2, 3 

Left or Right of z = 0 being 50% of the area under the standard normal curve...



As to z = .09, is placed slightly right of center on the standard normal curve..

Exel function NORMSDIST(.09) = .5359 , 54% to the left and 46% to the right
