3 (Sharpe-ratio) Suppose that X1, X2,..., is a lognormal geometric randomwalk with parameters (μ, o²). Specifically, suppose that X = Xo exp(rı +...Tk), where Xo is a fixed constant and r1, T2, ... are IID N(μ, o²). Findthe Sharpe-ratios of rk and log(Xk) — log(Xo) respectively, assuming therisk free return is 0.

Visitors come to a two-server location following a Poisson process with a rate of A. When they arrive, they join a common queue. The next person in line begins service as soon as a server finishes servicing the previous customer. The service times of server i are exponential RVs with rate μi, i=1; 2, where μ₁ + #2 > A. An arrival finding both servers free is equally likely to go to either one. 1. (10 pts) Define an appropriate continuous-time Markov chain for modeling this prob- lem. 2.

Use the data in vapor.csv, obtain the transformed predictor 1/X, and the transformed response log(Y), where "log" refers to the natural logarithm. Denote the new predictor by X*(=1/X) and denote the new response by Y*(=log Y). Fit a least squares model for the new response and the new predictor. It turns out that the estimated intercept is [ PUT ANSWER HERE ] , and the estimated slope is[ PUT ANSWER HERE ] .
