Chapter 2: Q 81. (page 143)

Normal states? The Normal probability plot displays data on the areas (in thousands of square miles) of each of the 50 states. Use the graph to determine if the distribution of land area is approximately Normal.

Short Answer

Expert verified

No, it is not approximately normal.

Step by step solution

01

Given information

The figure is:

02

Concept

The distance between the minimum and maximum values from the mean must be the same for the distribution to be normal.

03

Explanation

The data points in the provided image do not follow a linear trend, and curvature can also be seen in the provided normal probability plot. As a result, the distribution of land area could be described as non-normal.

Run fast! As part of a student project, high school students were asked to

sprint 50 yards and their times (in seconds) were recorded. A cumulative relative frequency graph of the sprint times is shown here.
