To find:
The type of data provided is categorical or numerical and also determine the type of display can be used to display the data with reason.

Answer to Problem 8E
It is a categorical data. Acircle graph can be used to display the data.
Explanation of Solution
Given information:
Consider the provided information,where a study determines the different amount of energy produced by different means, like natural gas, solar, wind, and electric.
Data collected by the study on energy produced by different means like , like natural gas solar, wind, and electric; comes under categorical data.
Therefore,
To display such categorical data,
