Question

**Chapter 5, Problem 6**

A population has a mean $\mu = 100$ and a standard deviation of $\sigma = 20$.

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

| X | z | | X | z |
|-----|----|---|-----|----|
| 108 | | | 115 | |
| 90 | | | 88 | |
| 130 | | | 95 | |

**Find the score (X value) that corresponds to each of the following z-scores.**

| X | z | | X | z |
|----|------|---|----|------|
| | -0.40| | | -0.50|
| | 0.75 | | | 1.80 |
| | 1.50 | | | -1.25|

Instructions: Calculate the z-scores using the formula:

\[ z = \frac{X - \mu}{\sigma} \]

For finding the X values corresponding to given z-scores, rearrange the formula:

\[ X = z \cdot \sigma + \mu \]

Complete the tables with your results.
