For a population with u=50 and o=8, find the z-score for x=54, x=42, x=62 ,x=48 ,x=52 ,x=34

Answer 1

I shall assume that u (usually typed as mu) is the mean and o (usually typed as sigma) is the standard deviation.

For x = 54, z = (54-50)/8 = +0.5

For x = 34, z = (34-50)/8 = -2

You do the others.
