Do students in early morning classes do more poorly than students in later classes? During one semester of Quan 2010, exam scores were averaged for one section of 28 students who met at 8:00am, and for another section of 37 students who met at 10:50am. The earlier section had a mean score of 80.6 with a variance of 103, while the later section had a mean score of 81.5 with a variance of 138.   

At a significance level of 0.10 can we conclude that 8:00am sections score lower than sections that meet at 10:50am?

In recent decades, the difference between the income going to the richest and poorest segments of the US population has been increasing.  

Since 1979, the after-tax income of the top 1% has increased by more than 250% while those among the bottom 20% have only seen an 11% increase. (Source: Statistical Abstract of the United States, 2010)

Does it matter if some groups have seen their income increase more rapidly than others?

Should the government impose higher taxes on the top 1% to try to shrink the "gap?"

Why or why not?

As a new analyst, you have calculated the following annual rates of return for the stocks of both Lauren Corporation and Kayleigh Industries.
Year Lauren’s Rate of Return Kayleigh’s Rate of Return
2007 5 5
2008 12 15
2009 −11 5
2010 10 7
2011 12 −10
Your manager suggests that because these companies produce similar products, you should continue your analysis by computing their covariance and coefficient of correlation. Calculate covariance and correlation for both companies and explain, would the combination of the common stock of Lauren and Kayleigh be good for diversification?

Using the high-low method, what are the estimated machine costs

1. if there are 1,100 Labour hours?
2. if there are zero Labour hours?
3. What is a significant drawback to using the High-low method to calculate costs at zero labour hours?

Remember, to be persuasive, you must use facts and logic. Identify the sources of information that you use, and don’t draw general conclusions from specific incidents.

The 2010 Supreme Court ruling in United States v. Comstock made it permissible to use civil commitment to further detain sexually dangerous offenders beyond their date of scheduled release. This means that a person can be convicted, sentenced, serve their entire sentence and be scheduled for release but still detained.

In your post, discuss what is supposed to be accomplished by this further detainment and how this detainment may be terminated. What are some of the requirements of this detainment, and are these requirements justifiable?
