Uranium in the Earth’s crust. Refer to the American Mineralogist (October 2009) study of the evolution of uranium minerals in the Earth’s crust, Exercise 5.9 (p. 230). Recall that researchers estimate that the trace amount of uranium x in reservoirs follows a uniform distribution ranging between 1 and 3 parts per million. In a random sample of n = 60 reservoirs, let  represent the sample mean amount of uranium.
a. Find E() and interpret its value.
b. Find Var().
c. Describe the shape of the sampling distribution of .
d. Find the probability that  is between 1.5 ppm and 2.5 ppm.
e. Find the probability that  exceeds 2.2 ppm.

Employment Law and the Hiring Process
After briefing the management team on employment law from Assignment 1, it is time to apply the knowledge to internal processes. There exist many fundamental legal concerns surrounding recruiting and the overall hiring processes within organizations. A current review of the company’s HR policies and procedures centered on employment law reveals some possible opportunities to improve the overall recruitment and hiring process. More pinpointed opportunities exist in background checks, employment tests, and hiring and promotions. If not properly administered, these areas may cause employment law issues within the company.
Write a six to eight (6-8) page paper in which you:
*Briefly explain your overall understanding of conducting employee background checks. Why are they done? Why are they important? Be clear with your discussion.
*Identify and discuss at least two (2) types of background checks you believe most organizations conduct and explain how you will ensure the types you select are properly administered in the company.
*List and describe at least five (5) employee drug testing procedures you should ensure in order to comply with state drug testing laws. How would you ensure adherence to the procedures?
*Briefly discuss your understanding of bona fide occupational qualification (BFOQ), affirmative action preferences, and promotions. Then, identify at least three (3) actions you would take to avoid employment law issues with these topics. Be specific.
Your assignment must follow these formatting requirements:
Be typed, double spaced, using Times New Roman font (size 12), with one-inch margins on all sides; citations and references must follow APA or school-specific format. Check with your professor for any additional instructions.
Include a cover page containing the title of the assignment, the student’s name, the professor’s name, the course title, and the date. The cover page and the reference page are not included in the required assignment page length.

Was the CNET story sufficient justification for the HP board’s actions? Why or why not?
2 HP Chairwoman Patricia Dunn defended the actions of the board by arguing that HP’S higher standards of corporate integrity justified such aggressive actions as pre-texting. Does its higher standards make the behavior of the board more or less ethical? Explain.
3 Does the fact that HP’s legal advisers approved the actions of Dunn and her board beforehand clear them of all responsibility in this case? Why or why not?
4 Does pre-texting match the founding principles of “the HP Way?
5 The board voted to dismiss Patricia Dunn in light of her indictment-was that the right decision? Why or why not?
