how much is 1 std dev?

anonymous · Answer

.95/2 + .68/2,  look at the pic to see that it makes sense

anonymous · Answer

Yeah, it does. 
When I did it, i tried to just do .68 + (.95/2)

anonymous · Answer

yeah but you would be adding .68/2 too much

anonymous · Answer

a) 	5%
	
b) 	95%
	
c) 	99.7%
	
d) 	None of these
These are the answers.
So would it be 81.5?

anonymous · Answer

.34 + .475 = .815, choice D

anonymous · Answer

Well alright. But now how would you figure out what percent scored over the 4.66?

anonymous · Answer

the normal is symmetric.  if .95 scored between .86 and 4.66, how much is left?

anonymous · Answer

.5?

anonymous · Answer

no. .05

anonymous · Answer

half of that is above 4.66 and half of that is below .86

anonymous · Answer

...Yeah that XD
I was thinking 5%, and I just didn't convert it all the way XD
so 2.5% were about the 4.66?

anonymous · Answer

above

anonymous · Answer

Above** XD
