Chapter 6, Problem 1RP

What is a density curve, and why are such curves important?

To determine

To define: The density curve.

To explain: The reason for the importance of the density curve.

Answer to Problem 1RP

The density curve defines the curve that identifies the shape of the distribution of the variable.

The reason for the importance of the density curve is “the density curves minimize the percentages of all possible observations”.

Explanation of Solution

If a curve identifies the shape of the distribution of the variable, then it is said to be a density curve. Also, the density curve is used to approximate the percentages of all the possible observations.
