Evaluate the integral: \int \frac{\sqrt{16x^2 - 49}}{x^3} dx (A) Which trig substitution is correct for this integral? $\circ x = \frac{1}{16} \sec(\theta)$ $\circ x = \frac{7}{4} \sin(\theta)$ $\circ x = \frac{4}{7} \sec(\theta)$ $\circ x = \frac{7}{4} \sec(\theta)$ $\circ x = \frac{49}{16} \sec(\theta)$ (B) Which integral do you obtain after substituting for $x$? Note: to enter $\theta$, type the word theta. $\int \text{ } d\theta$ (C) What is the value of the above integral in terms of $\theta$? \text{ } + C (D) What is the value of the original integral in terms of $x$? Note: WAMAP does not recognize the inverse secant (arcsec) function. You will need to use another inverse trig function when you fill in your answer below. \text{ } + C

Consider the Tobit model: $y^* = x\beta + u$, $u \sim N(0, \sigma^2)$, $y = max\{y^*, 0\}$, where we can observe $(y, x)$. Suppose that $(b, s^2)$ are the maximum likelihood estimators of $(\beta, \sigma^2)$ respectively. Then the model's fitted value is defined as: Oa. $xb$. Ob. $xb/s$. Oc. $y - xb/s$. Od. none of the other alternatives.
