Question

suppose 2500 students take a college exam the scores have a normal distribution with mean is 52 points and standard deviation 11 points for a score of 77 what is the z value

all z values can be found by calculating, using formula z = (x-μ) / σ

and this case is no different;  x = 77  μ = 52  σ = 11.
