**bobpursley**, Monday, June 23, 2008 at 9:48pma) One standard deviation is 16, that is a score of 84. 68 percent will have a score of 100+-16, so 34 percent will have a score from 84 to 100.

b. How many standard deviations is a score of 52?

**bobpursley**, Monday, June 23, 2008 at 9:54pmYes, of course it is. So how many standard deviations is it to a score of 52?

so would it be

100-16(3) =52

100-99.7=.03
