Chapter 6: Q. 23 (page 385)

Suppose X ~ N(12, 6). What is the z-score of x = 2?

Short Answer

Expert verified

The value of the zscore is -1.67

Step by step solution

01

Given Information 

Given in the question that, X~N(12,6)

x=2

We have to find thezscore

02

Explanation 

Let's consider the expression X~N(12,6)

Where,

渭=12

蟽=6

x=2

We can compute the zscore as follow:

z=x鈭�渭蟽

Place the given values in the above equation

Then,

z=2鈭�126

=鈭�106

=鈭�1.67
