Textbook Problem

In a population distribution, a score of X = 28 corresponds to z = –1.00 and a score of X = 34 corresponds to z = –0.50. Find the mean and standard deviation for the population. (Hint: Sketch the distribution and locate the two scores on your sketch.)

To determine

To find: The mean and standard deviation for sample.

Explanation

Given info: The z-score corresponding to X=28 is –1.00 and z-score corresponding to X=34 is –0.50.

Calculation:

The formula for calculating the mean for sample is,

M=Xzs

The formula for calculating the standard deviation for sample is,

s=Distance between two X scoresDistance between two z-scores

The standard deviation for sample is,

s=Distance between two X scoresDistance between two z-scores=34280
