But this doesn't make sense D: Why would they give it to me and I can't even solve it D:

dan815 · Answer

theres usually tables given with the sd and stuff leme see if its a simple one

dan815 · Answer

oh okay i see they already told  its 1 SD so

dan815 · Answer

so answer is A

dan815 · Answer

since 1 SD is approximately 34% so from both halfs approximately 68

anonymous · Answer

oh so if its given $$\sigma $$ so SD is considered 1 here

dan815 · Answer

yeah thats just the notation sd is given in multiples of that sigma

anonymous · Answer

yeah
@moemand  you got it?
