Question 1199281: If a set of data has a mean of 23.4 and a standard deviation of 2.9, what is the z-score for a value
of 30.1? Answer by Theo(13342) (Show Source):
You can put this solution on YOUR website! mean is equal 23.4 and standard deviation is equal to 2.9.
z-score for a value of 30.1 uses the z-score formula of z = (x - m) / s
z is the z-score
x is the raw score
m is the mean
s is the standard deviation
z = (x - m) / s becomes z = (30.1 - 23.4) / 2.9 = 2.31379 rounded to 5 decimal places.
