The waiting time \( X \) (in minutes) of a customer at a taxi rank has the following probability density function: \[ f(x)=\left\{\begin{array}{ll} 0.25 e^{-0.25 x} & \text { for } x \geq 0 \\ 0 & \text { otherwise } \end{array}\right. \] This is the exponential distribution with parameter \( \lambda=0.25 \). For this distribution, calculate the probability that the waiting time is: at most 0.5 standard deviations from its expected value.

1. Let’s say you are planning for a big vacation in four years. You estimate this exquisite trip will cost you $12,000. You plan on investing in bonds to ensure you have the cash on hand when it is time to finance the trip. Say you decided to purchase a 5-year 12% coupon bond that currently yields 8%APR. Its Macaulay Duration is 4.1542 years. b. What is the price of $1000 in the bond’s face value today? • c. If the interest remains at 8%APR, what is the time-4-year value of the coupon payments (on $1000 of face value) received in years 0 through 4? d. If the interest remains at 8%APR, what is the time-4-year value of the remaining bond cash flows (for $1000 of face value)? e. If the interest remains at 8%APR, what is the time-4-year total value of all expected cash flows per $1000 of face value (consider coupons, interest from reinvestment of coupons, and selling price of the bond)? f. If the interest remains at 8%APR, what is the time-4-year total value of all expected cash flows per $7544.44 of face value (consider coupons, interest from reinvestment of coupons, and selling price of the bond)? g. How does the value from part f compare to your trip cost? h. If tomorrow morning the interest rate on the bond shifts to 10%APR, what is the time-4-year value of the coupon payments received in years 0 through 4? i. If tomorrow morning the interest rate on the bond shifts to 10%APR, what is the time-4-year value of the remaining bond cash flows? j. If tomorrow morning the interest rate on the bond shifts to 10%APR, what is the time-4-year total value of all expected cash flows (consider coupons, interest from reinvestment of coupons, and selling price of the bond)? k. If tomorrow morning the interest rate on the bond shifts to 10%APR, what is the time-4-year total value of all expected cash flows per $7544.44 of face value (consider coupons, interest from reinvestment of coupons, and selling price of the bond)? l. How well did this investment strategy manage your interest rate risk?

In 1997, 4% of pregnant women nationally reported smoking more than 20 cigarettes (a \"pack\") during the course of their pregnancy. An obstetrician believes that this proportion has since decreased, with the increase in awareness about the dangers of smoking. To test this, they obtain patient records from 154 randomly selected pregnancies, and find only 3 women who reported smoking more than a pack of cigarettes over the course of their pregnancy. Use the normal approximation test of proportions to test the obstetrician's hypothesis, at the $\alpha = 0.10$ level of significance. On a separate sheet of paper, write down the hypotheses ($H_0$ and $H_\alpha$) to be tested. Conditions: np_0(1-p_0) = (Round to 3 decimal places.) The normal approximation test for proportions (is / is not) appropriate for this data. Rejection Region: To test the given hypotheses, we will use a (left / right / two) - tail test. The appropriate critical value(s) for this test is/are (Report your answer as it appears in Table V. For

Question 2 -- FOL, solve using resolution. We know the following information: • Frank owns cat Galaxy and rabbit Ears, i.e. person(Frank), cat(Galaxy), rabbit(Ears), own(Frank, Galaxy), own(Frank, Ears) • Every cat and every rabbit are animals, • Every pet owner is an animal lover, • No animal lover kills an animal, • Either Frank or cat Galaxy killed rabbit Ears. Besides already listed predicates you can use predicates animal(x), love(x,y), and kill(x, y) to state the knowledge base. No other predicates can be used to state the problem. Use resolution to answer the following question: Did a Galaxy kill Ears? • (50% of the credit) give CNF KB for the problem • (50% of the credit) show the resolution graph or spell the sequence of resolution operations Solution that does not use resolution gets no credit
