Chapter 2: Q 82. (page 143)

The density of the earth In 1798, the English scientist Henry Cavendish measured the density of the earth several times by careful work with a torsion balance. The variable recorded was the density of the earth as a multiple of the density of water. A Normal probability plot of the data is shown.16 Use the graph to determine if this distribution of density measurement 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.
