In your own words, explain how to obtain the “expected value of perfect information” for any payoff table, which has probabilities associated with each state of nature. Then, provide an example

Define and explain the "Hall's effect" in magnetism. What important physical properties of the charge carriers were found with the help of this effect? ii) Consider a strip of copper immersed in a magnetic field B carrying a current i as shown in figure (1). Explain how the polarities are produced on opposite sides of the strip? iii) How the Hall Potential ∆VH and the Hall's Electric Field EH are measured? iv) When the equilibrium condition is reached, no further charge flow occurs. Use Lorentz force for equilibrium state, find an equation for the density “n” of the charge carriers.

Various reform groups with various causes developed in the US in the late 1800s and early 1900s; these are loosely called “Progressives” as they aimed to use government policies or science to improve and advance society. Also, this period was a time when the US started as a major player in international conflicts—first in the “Spanish American War and then in World War I. There were deep isolationist sentiments about such overseas entanglements, and President Wilson first has one position and then the other. Choose and discuss (in a full paragraph or two) one of the following two topics related to the late 1800s and early 1900s.

In the Progressive Era (roughly 1890–1920), multiple groups advocated for reforms in various aspects of government, society, and the economy. Discuss here the “muckrakers” and Taylor’s “scientific management”. Explain briefly the approach and aim of the “muckrakers” and that of F. W. Taylor. Compare their approaches and describe your feelings about them, and relate some modern situation that reminds you of one of these approaches and reform causes. Identify the source(s) where you read about the reform cause.

From the text, Wilson did not maintain his own campaign slogan (“He kept us out of war”). Explain with some specifics why Wilson became pro-war. Describe your own feelings on that issue when you look back at it, and whether he was right to change. Briefly, identify a similar international consideration today—or of the last 20 years, and what lesson might be drawn from the example in Wilson’s time. Identify the source(s) where you read about Wilson.

Amy, a single individual and sole shareholder of Brown Corporation, sold all of the Brown stock for $30,000. Amy's stock basis was $150,000. She had owned the stock for 3 years. Brown Corporation meets the Section 1244 requirements. 1) How much of an ordinary loss does Amy have? 2) How much of a capital loss does Amy have? 3) Do your answers above change if Amy is married? Explain how.

City residents complain about the noisy customers of the city’s bars. The Council decides to fine each bar in the area a fixed amount of $100. Assume Joe's Bar is just one of many in the area so the perfect competition model can be used.

a. Use graphs to show the effect of the fine on the price charged, the quantity of drinks served and the profits at Joe's in the short run and long run.

b. How would your answer to a be different if Joe’s Bar was the only one in the city? (i.e. Joe’s bar has a monopoly) Explain your answer.

c. Is the noise created by Joe’s customers an externality? Explain. Will the tax increase or decrease deadwight loss?

a) Please describe in detail what PROFITABILITY RATIO attempt to measure?

b) Where would you obtain such information?

c) For what period of time and what other comparisons would assist your analysis.

d) What management policies would have a positive affect on this analysis tool?

Please do part B-D

Does the ability to empathize-the capacity to understand and experience the emotional states of another person-increase with age? A researcher gave a test of empathy to a group of 20 first graders and then re-tested these same children when they were in the sixth grade.

State for each:

a. the null hypothesis

b. whether you would analyze the data with the t test for two independent samples or the t test for two related samples.

c. Explain the basis for your selection of the statistical test.

d. Also state for each study whether the researcher could reasonably conclude that the difference in the independent variable was causally responsible for differences in the dependent variable. Explain the basis for your answer.

Position Statements Choose five (5) of the following questions to answer in about 100 words each. Simply state and briefly explain your position on the issue prior to our formal study of it. No comprehensive, developed argument is needed at this time, simply a coherent expression of your view. 1. Is abortion a moral or immoral choice? Do you consider yourself pro-life or pro-choice? 2.

What is the proper response to hate speech? Is it justifiable to ban or prohibit some types of speech in certain contexts? 5. Is pre-marital sex a moral choice? Or should one wait until marriage? 6. Is capital punishment (the death penalty) an ethically appropriate punishment? 7. Should we acknowledge and respect basic rights (such as the right to life) for nonhuman animals? 8.
