The value of the z score for a mean of 4 and the standard deviation is 1.
The z score determines the value of standard deviation which is how much above or below the raw data. The formula is given as
[tex]Z=\dfrac{X-\mu}{\sigma }[/tex]
here
x is the raw score,
μ is the mean and σ is the standard deviation.
If we assume the values
μ = 4, σ = 2, hence for x = 6:
[tex]Z=\dfrac{6-4}{2} =1[/tex]
Thus the value of z score for the assumed value of μ = 4, σ = 2, hence for x = 6 will be z=1
