5).Find the five-number summary for the data on highway mileage shown below.

In California and many other states, there is a severe drought. What has happened to the supply curve of water? If there is a shortage of water, what will happen to the price of water? Do you agree that this change in the price of water is the best way to eliminate the shortage? Is this a fair way to reduce the shortage? Do you have any other ideas to eliminate the shortage? How will the drought impact agricultural goods' supply curves and their prices?

Derive the density of states for free electrons as a function of energy E in 1) one-dimension, 2) twodimension, and 3) three-dimension (N=total number of electrons, m=electron mass, V=volume of solid) (Hint: First, derive the total number of electrons as a function of k)

Milton Friedman:

States that there is only one social responsibility that organizations have and that is to use its resources and engage in activities designed to increase profits. Therefore, there is no need for corporate social responsibility as the organizations main goal is profit- making.

With this view organizations have four responsibilities.

1. Discuss the four responsibilities in their orders.

A Rydberg atom is an atom whose valence electrons are in states with a very large principal quantum number n. This means it has a probability cloud with a large amplitude a large distance from the nucleus. Evidence of such atoms has been detected by radio astronomers in the form of radiation from diffuse hydrogen gas in intersellar space. In fact, there is no theoritical limit on the size an atom can attain, provided it is free from outside influences.

1) What is the smallest value of n such that the Bohr radius of a single such hydrogen atom would be greater than 8.5 microns, roughly the size of a typical single-celled organism.

E_e = 400.85

2) What is the wavelength of radiation this atom emits when its electron drops from the n level calculated in part (1) to the n-1 level?

λ₁ = m

3) What is the wavelength of radiation this atom emits when its electron drops from the n level calculated in part (1) the n-2 level?

λ₂ =

What is the wavelength of radiation this atom emits when its electron drops from the n-1 level the n-2 level?

λ₃ =

Consider the world with two countries: Country A and Country B. There are two states of the world: State 1 and State 2. In State 1, output of Country A is $100 billion, and output of Country B is $80 billion. In State 2, output of Country A is $70 billion, and output of Country B is $120 billion. Assume that the share of labor income in output is 70% for Country A and 60% for Country B, respectively.

a.)Derive the income distribution in each country in each state when there is no foreign direct investment.

b.)Consider foreign direct investment such that residents in each country hold 50% of domestic portfolio and 50% of foreign portfolio. Derive the income distribution in each country in each state in this case.

c.)Based on your answers in Parts (a) and (b), does foreign direct investment help residents in the two countries diversify income risk? Explain your reasoning.

Draw the internuclear potential as a function of nuclear separation for the ground and excited states of a molecule where the equilibrium separation of the (bound) excited state is smaller than that in the ground state. Draw in the vibrational levels for each state, the electronic transition from the ground vibrational state, and the dissociation energies for each electronic state. What should the spectrum look like?

A 2006 report of the U.S. Surgeon General states that "there is no risk-free level of exposure to secondhand smoke. Nonsmokers exposed to secondhand smoke at home or work increase their risk of developing heart disease by 25 to 30 percent and lung cancer by 20 to 30 percent. The finding is of major public health concern due to the fact that nearly half of all nonsmoking Americans are still regularly exposed to secondhand smoke."

Consider the following data from the U.S. Department of Health and Human Services, National Center for Health Statistics, Third National Health and Nutrition Examination Survey. All values are measured levels of serum cotinine (in ng/ml), a metabolite of nicotine—when nicotine is absorbed by the body, cotinine in produced.

Smokers = subjects reported tobacco use

ETS = nonsmokers exposed to environmental tobacco smoke at home or work

No ETS = nonsmokers with no exposure to environmental tobacco smoke at home or work

Use a Kruskal-Wallis test with a 0.05 significance level to test the claim that the median cotinine levels are not all equal for these three groups. What do the results suggest about secondhand smoke?

Efficient market hypothesis (EMH) states that the price of a security (such as a share) accurately reflects the information available. When information arrives, how fast will an information about a share be captured and reflected in the share price depends on the degree of competition among market investors. List and briefly explain, in your own words, two variations of information.
