Textbook Problem

A sample has a mean of* M =* 25 and a standard deviation of *s* = 5. For this sample, find the *X* value corresponding to each of the following *z*-scores.

z = 0.40 |
z = 1.20 |
z = 2.00 |

z = –0.80 |
z = –0.60 |
z = –1.40 |

To determine

**To find:** The *X* value corresponding to *z*-scores.

Explanation

**Given Info:**

The sample has mean

**Calculation:**

The *z*-score is used to transform any distribution in to standardized distribution with a predetermined mean and a predetermined standard deviation.

The formula for specified value of *X* is,

Substitute

The *X* value corresponding

The *X* value corresponding

The *X* value corresponding
