INTRODUCTIONStatistics is related with the process of collecting, measuring, evaluating and interpretation of allthe numerical as well as quantitative data for gaining deep insight about a particularphenomenon. Making correct and proper interpretation of data with the help of statistical as wellas mathematical tools can help in better understanding and thus can assist in making crucialbusiness decisions as well. The present report is based on statistical and research methods whichare helpful in decision making process of the business. It will define about comparison as madeabout Co 2 emissions from the fossil fuels in the year 2009 and 2013 with the help of graphicalmethods. Furthermore, with the help of frequency distribution, ogive and related statistical toolsexplanation about time required by assembly line workers will be made. At last, with the help ofdescriptive statistical analysis data will be arranged and interpreted in proper and effectivemanner.MAIN BODYQuestion 1a.

Interpretation-From the above analysis it has been interpreted that carbon emission bythe producers in most of the countries has been reduced over the years from 2009 to 2013.However, there are some countries within which the emission of carbon has increased such aschina, Russia, Japan, India etc. In united states, carbon emission had shown a declining trendwith greater value leads to negative amount equates to -657 over the years. This helped thecountry in preventing the premature deaths and it creates a polluting free environment which inturn benefits the society as well. From the year 2009 to 2013, it has been assessed that carbonemission in china has increased with a higher value resulting to 5007.b.
