Consider a normal population with μ = 47 and σ = 5.2. Calculate the z-score for an x of 45.7 from a sample of size 25.
----------------------
Note: The fact that you have designated x = 45.7 means
it is a population element and not a sample mean.
--------------------------------------------
If you meant it to be a sample mean you should designate it as x-bar.
--------------------------
z(45.7) = (45.7-47)/5.2 = -0.25
