Textbook Problem

A distribution of English exam scores has μ = 50 and σ = 12. A distribution of history exam scores has μ = 58 and σ = 4. For which exam would a score of *X* = 62 have a higher standing? Explain your answer.

To determine

**To explain:** The exam for which the score

Explanation

**Given Info:**

The English exam score has a mean of

The distribution of history exam has a mean of

The *X*-score is 62.

**Calculation:**

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

Use the formula of z-score to transform the original raw scores into z-scores as follows:

**For English Exam:**

Substitute the value 62 for *X*, 50 for
