Answer #1

Although the archelogical evidneces which suggest that all human beings were originated in Africa and from there all human beings were dispersed to other parts of the would including Asia and other parts. With time, it has been seen that the evolutionary changes observed in the archeological evidences share similarities between these ancestral forms.

Although these evidences support this hypothesis, high-throughput screening with genome-wide comparison would be a better and reliable method for conducting research, analysis and validation of the hypothesis. Accordingly, the ancestors of all the human races present today can be traced using these genome analyses and hence would provide a better proof for the assurance of this hypothesis.

Recent evidence suggests that graduating from college during bad economic times can impact the graduate's earning power for a long time (Financial Times, June 1, 2012). An associate dean at a prestigious college wants to determine if the starting salary of his college graduates has declined from 2008 to 2010. He expects the variance of the salaries to be different between these two years. The data are shown in the accompanying table and are contained in the accompanying Excel file....

Through careful genetic engineering, you have produced what you call the Super Tree – a tree that can absorb extraordinary amounts of carbon dioxide (CO2), thereby helping to slow the process of global warming. Past research has shown that a regular tree absorbs 48 pounds of (CO2) per year but you find that in a random sample of 16 of your own Super Trees, the average amount of CO2absorbed is 54.3 pounds with a standard deviation of 18.
