Chapter 6: Q.22 (page 385)

Suppose X ~ N(鈥�1, 2). What is the z-score of x = 2.

Short Answer

Expert verified

The value ofzscore is1.5

Step by step solution

01

Given Information 

Given in the question that X~N(鈭�1,2)

x=2

We have to find the zscore.

02

Explanation 

Let's consider the expression X~N(鈭�1,2)

Where,

渭=-1

蟽=2

Now, we can compute the zscore as follow:

z=x鈭�渭蟽

Place the given values in the above equation.

Then,

z=2鈭�(鈭�1)2

=2+12

=32

Simplify,

localid="1648722577874" z=1.5
