Suppose X ~ N(9, 3). What is the z-score of x = 9?

Short Answer

Expert verified

The value of thezscore is0.

Step by step solution

01

Given information 

Given in the question that, X~N(9,3)

x=9

We have to find thezscore.

02

Explanation 

Let's consider the expression X~N(9,3)

where,

x=9

渭=9

蟽=3

We can compute the zscore value as follow:

z=x鈭�渭蟽

Place the given values in the above equation:

z=9鈭�93

=03

=0
