Suppose X ~ N(2, 3). What value of x has a z-score of 鈥�0.67?

Short Answer

Expert verified

The value of x is-0.01

Step by step solution

01

Ste 1 Given Information

Given that

z=-0.67And,

X~N(2,3)Where,

渭=2

蟽=3

02

Explanation

The z-score is defined as below:

z=x-渭蟽

To find the x-value corresponding to z=-0.67,put the provided values in the above expression. Then,

-0.67=x-23

x-2=-0.67脳3

x=-2.01+2

x=-0.01
