(a) X = -3; X= -9; S = ?; IQ = 130

(b) X = -.5; X=? ; S = .5; SAT = 800

(c) X = ?; X= 50; S = 12; IQ = 85

(d) X = 60; X= 62; S= ?; SAT = 450

(e) X = 52; X= 40; S = 6; IQ= ?

I tried using the z-score formula and solving for the missing values, but the numbers I got were defiantly not right. Is there a different way to solve them or did I just mess up doing it the first time?
