Textbook Problem

In a sample distribution, X = 56 corresponds to z = 1.00, and X = 47 corresponds to z= –0.50. Find the mean and standard deviation for the sample.

To determine

To find: The mean and standard deviation for sample.

Explanation

Given info:

The data represents two z-score values of the sample correspond to the X-value. The z-score corresponding to X=56 is 1.00 and z-score corresponding to X=47 is 0.50.

Calculation:

The general formula for calculating the mean for sample is,

M=Xzs

The mean for sample is,

M=Xzs=56(1.00×6)=50

Thus, the mean for the sample is 50
