7 Question 5 Suppose that $T_1, \dots, T_n$ are independent and that each is distributed Exp($\lambda$). We denote with $\bar{T}_n$ the sample mean based on these observations and we introduced: $\hat{\lambda} = \frac{1}{\bar{T}_n} = \frac{n}{\sum T_i}$ and $\hat{\lambda}_2 = \sqrt{\frac{2n}{\sum T_i^2}}$ (i) Calculate the variance of $T^2$ where T is distributed Exp($\lambda$). (ii) What is the central limit theorem for $\sum T_i^2 / n$? (iii) Using the delta method, derive the corresponding convergence in distribution result for $\hat{\lambda}_2$. Recall that we derived this for $\hat{\lambda}$ in class.

A sheet of infinite moving charge and a point charge A very large metal sheet has charge moving over it. The sheet has a surface charge density of $\sigma$ = 5x10$^{-6}$ C/m$^2$. The charges on the sheet are moving at an average speed of $v_s$ = 0.0001 m/s. A proton is located a distance D = 10 cm from the sheet. The proton is headed straight at the sheet with a speed of $v_e$ = 10000 m/s. a) What is electric field above the sheet at the point the proton is at (magnitude and direction)? b) What is the surface current density of the sheet? c) What is the magnetic field above the sheet at the point the proton is at (magnitude and direction)? d) What is the electro-static force on the proton (magnitude and direction)? e) What is the magnetic force on the proton (magnitude and direction)? f) How does the electro-static force compare to the magnetic force (which is bigger and by how many times bigger is it)? g) Approximately how close will the proton get to the plate? (is there a force you can neglect?)

Video Transcript: >> You've built all of this ->> Kevin O'Neal: Right ->> Building things is in Kevin O'Neal's DNA. Lincoln Center and other iconic buildings in New York, and this horse farm, an American Dream for his wife and three kids in rural New Jersey. But there's no demand for O'Neal's skills these days ->> Well, did you ever imagine you'd have to leave your country to provide sustenance for yourself and your family?>> Kevin O'Neal: Never. Never in my wildest dreams. This is Chester.>> Across thirty years, O'Neal made his name as a top construction manager in New York, but the financial crisis shut everything down. O'Neal couldn't get a nibble. Then in 2008, a call from halfway around the world, the Middle Eastern Emirate of Dubai ->> So how did they find you?>> Kevin O'Neal: The recruiter who was given a mandate to find one of the most difficult ornery son of a bitches in New York that got things done ->> He jumps at the chance ->> Kevin O'Neal: I was very reluctant until I saw the job. To me, it was like building the pyramids again. When I went to Dubai, I said OK. You know. I'll do for a short period. If the job doesn't pan out, I can always come back home, and then things will get better, and I'll go back to work. When I came home, things were worse.>> Recruiter David Cohen-Gorum says men like O'Neal must be ready to move abroad ->> David Cohen-Gorum: Since the beginning of the recession, we've seen an increase of about fivefold in construction professionals looking to move outside of the country for a job.>> Kevin O'Neal: I'm frustrated. I'm upset, but you still got to make a living. So I do what I have to do. I hate it. I hate not being in America.>> Kevin O'Neal: Destination?>> Yes.>> Kevin O'Neal: Heathrow.>> This week, O'Neal left America for England, where he's interviewing for a job. The job is 10,000 miles away from home in Australia. After watching the video on an American working in Dubai and reading the New York Times article where Chris Pavone reflects on his experiences working in Luxembourg, answer the following questions: 1. What kind of staffing approach is being used by Dubai? Explain. 2. What does Kevin O'Neal, as an expatriate, bring to Dubai? How does this differ from Chris Pavone's situation? 3. What characteristics do recruiters look for in expatriates? 4. How might compensation differ between expatriate Kevin O'Neal and an inpatriate? 5. How do HR personnel/recruiters develop a global mindset?
