15 pts] 1. Suppose the demand for coffee is given by the following equation: $Q^d = 280 - 40P$ and the supply equation is $Q^s = 80 + 10P$, where $P$ is the price in dollars and $Q^d$ and $Q^s$ respectively, are quantity demanded and quantity supplied. a. Derive the supply and demand curves. Determine the equilibrium price and equilibrium quantity of coffee. b. Suppose a price ceiling of $2.50 is imposed on the market, compute the quantity demanded and the quantity supplied. What is the difference called? c. Suppose an excise tax of $2.00 per unit is imposed on the seller. Determine the new equilibrium price and quantity. What price will the seller receive?

4. The time it takes travelers to pass through security at a large airport is approximately normal with a mean of 25 minutes and a standard deviation of 8 minutes. Let the random variable X be the time a randomly selected traveler takes to pass through security. a. What is the proportion of travelers who are able to pass through security in 15 minutes or less? b. What is the proportion of travelers who take between 25 and 45 minutes to pass through security? c. In a study of security measures at this airport, a random sample of 25 travelers will be selected and the time they take to pass through security will be recorded. The mean of this sample, ar{X}, will also be calculated. What is the sampling distribution of ar{X}? Be sure to specify the parameters of this distribution.

Problem 2: A (battery) system has the state equation $\dot{x} = \begin{bmatrix} 0 & 0 \\ 0 & -\frac{1}{R_p C_p} \end{bmatrix} x + \begin{bmatrix} \frac{1}{Q} \\ \frac{1}{C_p} \end{bmatrix} i$ v = [c, 1]x where Q = 36000, $C_p$ = 500, $R_p$ = 0.2, c = 0.5. (1) Check if the system is observable. (2) Design a state observer to estimate x (we need to estimate the SOC), such that the observation error dynamic system has poles at -1, -2.
