Chapter 2.2, Problem 74E

To determine

Discuss the distribution of the percent of foreign − born residents in the state is not approximately normal.

Answer to Problem 74E

The distribution has been skewed to the right instead of roughly symmetric.

Explanation of Solution

Given information:

  

The Normal distribution possesses the property that the distribution is symmetric.

The distribution in the histogram shown has been skewed to the right; we can also see that in the histogram, most of the dots lie to the left, along with a tail of less usual values to the right.

We know that

The Normal distribution should be symmetric.

And

This distribution has been skewed to the right.

We can say

This distribution is not approximately the Normal distribution.
