For a population with μ = 60 and σ = 12,

a. Find the z-score for each of the following X values. (Note: You should be able to find these values using the definition of a z-score.

You should not need to use a formula or do any serious calculations.)

X = 75 X = 48 X = 84 X = 54 X = 78 X = 51

b. Find the score (X value) that corresponds to each of the following z-scores. (Again, you should not need a formula or any serious calculations.)

z = 1.00 z = 0.25 z = 1.50 z = −0.50 z = −1.25 z = −2.50
