If you are given a raw score of X 35 when the population me

If you are given a raw score of X = 35 when the population mean is = 30 and the standard deviation is equal to = 5, what is the z-score for this raw score?

a.z = 1.00

b.z = 5.00

c.z = 25.00

d.z = 0.00

Solution

The z score for this raw score is:

z=(X-mu)/sigma=(35-30)/5
