For a population with a mean of µ=60 and standard deviation of Ợ=24, find the z=score corresponding to each of the following samples

a. M=63 for sample of n=16 scores
b. M=63 for sample of n=36 scores
c. M=63 for sample of n=64 scores

1 answer

I assume this is for a distribution of means.

Z = (score-mean)/SEm

SEm = SD/√n

Plug in data and solve for Z.
