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

• math -

'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

• math -

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