Burning fuels in power plants and motor vehicles emit carbon dioxide (CO2), contributing to global warming. The table at the right displays CO2 emissions per person from countries with at least 20 million populations. (a) What is the variable of interest? How do you classify it? (b) Make a histogram of the data using classes of width 2, starting at 0. Show the frequency distribution table and create the Histogram of the data. Be mindful of submitting a correct graph. (c) Describe the shape, center, and spread of the distribution. Which countries are outliers? For a description of the shape, center, and spread, put your response in paragraph form. Select the most appropriate measure of center and measure of spread to describe the distribution. Also, do not forget to interpret the values based on the given context. Lastly, do not forget to include the unit of measurements. For outliers, show your method of how you were able to determine these. What can you say about these countries?
I WILL UPVOTE IF IT IS ORIGINAL, COMPLETE, CORRECT, OR TYPEWRITTEN. THANK YOU VERY MUCH.

(b) Make a histogram of the data using classes of width 2, starting at 0.
- Show the frequency distribution table and create the Histogram of the data. Be mindful of submitting a correct graph.
(c) Describe the shape, center, and spread of the distribution. Which countries are outliers?
- For a description of the shape, center, and spread, put your response in paragraph form.
- Select the most appropriate measure of center and measure of spread to describe the distribution. Also, do not forget to interpret the values based on the given context.
- Lastly, do not forget to include the unit of measurements.
- For outliers, show your method of how you were able to determine these. What can you say about these countries?
(d) Include some reflections and make at least two workable measures for this environmental concern.
