What is the area to the right of three?

Short Answer

Expert verified

The area to the right of the three can be represented asP(x>3)or1-P(x<3)

Step by step solution

01

Given Information

Given in the question is a graph:

We have to find what is the area to the right of three

02

Explanation

The area to the left of the normal probability represented as P(x<x)

The area to the right of the normal probability represented as P(x>x)

Therefore, we can represent the area to the right of three in a probability statement asP(x>3)or1-P(X<3)

a. Suppose a 15 to 18-year-old male from Chile was 176cm tall from 2009to 2010. The z-score when x=176 cm isz= _______. This z-score tells you that x=176cm is ________ standard deviations to the ________ (right or left) of the mean _____ (What is the mean?). b. Suppose that the height of a 15 to 18-year-old male from Chile from2009 to 2010 has a z-score of z=–2. What is the male’s height? The z-score(z=–2) tells you that the male’s height is ________ standard deviations to the __________ (right or left) of the mean.
