Textbook Problem

Find each of the requested values for a population with a mean of

**a.** What is the z -score corresponding to X = 52?

**b.** What is the *X* value corresponding to z = -0.50?

**c.** If all of the scores in the population are transformed into z-scores, what will be the values for the mean and standard deviation for the complete set of scores^{?}

**d.** What is the z-score corresponding to a sample mean of *M* = 42 for a sample of n = 4 scares?

**e.** What is the z-score corresponding to a sample mean of *M* = 42 for a sample of *n* = 16 scores?

**a.**

To determine

**To find:** The value of *z* when

Explanation

**Given info:**

Score follows normal distribution with mean 50 and standard deviation 20.

**Calculation:**

Let
