Textbook Problem

For a population with *μ*= 80 and σ= 10,

**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* = 100

*X* = 60

*X* = 95

*X* = 50

*X =* 85

**a.**

To determine

**To find:** The z score corresponding to *X.*

Explanation

**Given info:** The population has mean

**Calculation:**

The formula for *z* score is,

The *z* score corresponding to

Thus, the value of *z* is –0.5.

The *z* score corresponding to

Thus, the value of *z* is 1.5.

The *z* score corresponding to

Thus, the value of *z* is 2

**b.**

To determine

**To find:** The *X* score corresponding to *z.*
