Global warming seems largely a result of human activity that produces carbon dioxide emissions and other greenhouse gases. From data.worldbank.org, emissions

(per capita) in 2010–2014 for the eight largest countries in population size were in metric tons (1000 kilograms)

per person: Bangladesh 0.4, Brazil 2.2, China 6.2, India 1.7, Indonesia 1.8, Pakistan 0.9, Russia 12.2, and United States 17.6.

(a) For these eight values, find the mean and the median.

(b) For comparison, Qatar had a value of 40.3.

Evaluate the impact of this outlier on how the mean and median change for the full data set with n = 9 compared to the original data.
