Question

a population has u= 80 and o= 10.

Find the z-score for each of the following X values.

A population has Mu = 80 and sigma = 10. 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 detailed calculations.) Find the score (X value) that corresponds to each of the following z-scores. (Again, you should be able to find these values without any formula or detailed calculations.)

Explanation / Answer

The formula for converting x score to z score is

-------------------------------------------

mu =80 and sigma=10

Next set is x = Mu + z*sigma

x Z 75 -0.5 95 1.5 100 2 50 -3 60 -2 85 0.5
