Suppose X and Y are independent and identically distributed log-normally distributed random variables, each with density $$f_\sigma(t) = \frac{1}{t} \frac{1}{\sqrt{2\pi\sigma^2}} \exp\left(-\frac{(\ln(t))^2}{2\sigma^2}\right) \quad \text{for } t > 0,$$ where $\sigma$, $0 < \sigma \le 3$, is unknown. (a) For every $(x, y)$ find and simplify the corresponding likelihood function $\ell_{x,y}$. (b) Sketch the graph of $\ell_{x,y}$. (c) Which model would you pick if $\{(X, Y) = (17, 29)\}$ was observed?

Solve the following questions on a paper, scan (or take photo) and upload below. f(t) M1 0000 B1 XXXXX K1 M2 K2 B2 The mechanical structure of a system is given as shown together with the given parameters. $M$ shows the masses, $K$ shows the spring coefficients and $B$ shows the viscous damping coefficients. An external force $f(t)$ is applied to the mass as shown. a) (30p) Indicate the displacement variables \"x..\" assuming they are along the $f(t)$ direction. Draw the free-body diagram for only $M2$ and write all the forces effecting on it. b) (50p) Write the equations of motion for the whole system in Laplace domain using the impedances (use direct method).
