3. Suppose that the profit $P(x)$ (in hundreds of dollars) from selling $x$ units of a product is given by $P(x) = \frac{x^2}{2x + 1}$ (a) Find and interpret the marginal profit when 4 units are sold. (b) What is happening to the marginal profit as the number sold increases? (c) Find and interpret the marginal average profit when 4 units are sold. 4. If a sum of $1000 is deposited into an account that pays $r\%$ interest compounded quarterly, the balance after 12 years is given by $A(r) = 1000 \left(1 + \frac{r}{400}\right)^{48}$. Find and interpret $\frac{d}{dr}A(r)$ when $r = 5$.

2. Suppose E(X1) = E(X2) = ?, Var(X1) = 4, Var(X2) = 9 and Cov(X1, X2) = 1. Your goal is to estimate the unknown mean ?. (a) Consider an unbiased estimator of the form: \(\hat{\mu} = aX_1 + (1 - a)X_2\). What value should be chosen for the constant a in order to minimize the mean squared error of \(\hat{\mu}\)? (b) What is the relative efficiency of \(\hat{\mu}\) (for the value of a you found) with respect to the estimator \(\hat{\mu}_0 = X_1\)?
