If you know the z score, standard deviation, and mean, what formula would you use to compute the raw score?
A) $X = ( \ { z } + s ) / \bar { X }$
B) $\bar { X } = z ( s ) + X$
C) $X = z ( s ) + \bar { X }$
D) $z = \bar { X } - X / s$

The formula to compute the raw score when the z score, standard deviation, and mean are known is X = z(s) + mean. This formula takes the z score, multiplies it by the standard deviation, and adds it to the mean to find the raw score. Therefore, the correct choice is C.

If You Know the Z Score, Standard Deviation, and Mean X=( z+s)/XˉX = ( \ { z } + s ) / \bar { X }X=( z+s)/Xˉ

If You Know the Z Score, Standard Deviation, and Mean $X = ( \ { z } + s ) / \bar { X }$
