what is the z-score for the given raw score, mean and standard deviation, assume a normal probability dist. raw score=66,u=60, and 0=6 u and o are those wierd symbols is the answer 1, 10, 6, or 66

'u' = mu 'o' = sigma (Be sure to write them correctly when turning your work in). The z score can be found by z = (x-u)/o z = (66 - 60)/6 z = 1

Z = (x-μ)/SD, where x = raw score, μ = mean and SD = standard deviation.
