Suppose stock returns can be explained by the following three-factor model: Ri = RF + \beta 1F1 + \beta 2F2 − \beta 3F3 Assume there is no firm-specific risk. The information for each stock is presented here: \beta 1 \beta 2 \beta 3 Stock A 1.55 .75 .30 Stock B .85 1.55 −.50 Stock C .79 −.26 1.35 The risk premiums for the factors are 6.7 percent, 5.9 percent, and 6.3 percent, respectively. You create a portfolio with 20 percent invested in Stock A, 20 percent invested in Stock B, and the remainder in Stock C. The risk-free rate is 3.8 percent. What is the beta for each factor for the return on your portfolio? (Do not round intermediate calculations and round your answers to 2 decimal places, e.g., 32.16.) What is the expected return on your portfolio? (Do not round intermediate calculations and enter your answer as a percent rounded to 2 decimal places, e.g., 32.16.)

Nataraj (2007) finds that a 100% increase in the price of water for heavy users in Santa Cruz caused the quantity of water they demanded to fall by an average of 30%. (Before the increase, heavy users initially paid $1.55 per unit, but afterwards they paid $3.10 per unit.) In percentage terms, how much did their water expenditure (price times quantity)—which is the water company's revenue—change? With the price increase, the company's revenue changed by %. (Enter your answer rounded to two decimal places.

2) Consider the atmosphere of the Earth and Moon. Using your knowledge of molecular speeds, "matlab" and gravity, find the following and comment on your results, etc. You must use matlab//another program to perform the computations. (40 points\u201310 per each of the 4 parts.) MKS Masses: $5.98 \times 10^{24}$ and $7.36 \times 10^{22}$ & Radius: $6.37 \times 10^6$ and $1.74 \times 10^6$ a) Calculate the escape velocity of a projectile at the surface of the Earth. Discuss your method. Show your work/derivation/assumptions of the formula. No matlab here. b) The T of the Earth's upper atmosphere is actually pretty high; say 1000 K. Find the (normalized\u2014 which you need to verify!) probability of a nitrogen molecule at this T moving faster than the escape velocity. You will need to use matlab. Comment! In other words, consider a system of N2 gas at equilibrium at 1000K. You know what its speed distribution looks like. What is the probability of finding a nitrogen with a speed > the escape speed?
