1. The provost at the University of Chicago claimed that the entering class this year is larger than the entering class from previous years but their mean SAT score is lower than previous years. He took a sample of 20 of this year’s entering students and found that their mean SAT score is 1,501 with a standard deviation of 53. The University’s record indicates that the mean SAT score for entering students from previous years is 1,520. He wants to find out if his claim is supported by the evidence at a 5% level of significance. Round final answers to two decimal places. Solutions only.
(A) The parameter the president is interested in is:
(a) the mean number of entering students to his university this
year.
(b) the mean number of entering students to all U.S. universities
this year.
(c) the mean SAT score of the entering students to his university
this year.
(d) the mean SAT score of the entering students to all U.S.
universities this year.
(e) None of the above.
(B) The population the president is interested in is:
(a) all entering students to all universities in the U.S this
year.
(b) all entering students to his university this year.
(c) all SAT test centers in the U.S. this year.
(d) the SAT scores of all students entering universities in the
U.S. this year.
(e) None of the above.
(F) True, False, or Uncertain: The null hypothesis would be rejected.
(G) True, False, or Uncertain: The null hypothesis would be rejected if a 10% probability of committing a Type I error is allowed.
(I) True, False, or Uncertain: The evidence proves beyond a doubt that the mean SAT score of the entering class this year is lower than previous years.
(J) True, False, or Uncertain: If these data were used to perform a two-tail test, the p-value would be 0.1254.

Create a class Mammal with the following UML
diagrams:
+---------------------------------+
| Mammal |
+---------------------------------+
| - name: String |
+---------------------------------+
| + Mammal(String name) |
| + getName(): String |
| + isCookable(): boolean |
| + testMammal(): void | (this method is static
)
+---------------------------------+
The isCookable method of the
Mammal class returns a boolean indicating whether
the mammal can be cooked or not: some mammals can be cooked and
some mammals cannot be cooked so for safety reasons the
isCookable method just prints a message
"Do not cook this!" and returns false (because the
isCookablemethod must return a boolean).
Add a class Human to your program. A human is a
mammal. The constructor for the Human class takes
no argument. All humans are named "Alice" and
humans cannot be cooked (the isCookable method
must not print any message though, it simply returns
false).
Add a class Rabbit to your program. A rabbit is a
mammal. The Rabbit class has a private instance
variable weight of type double
that describes the weight of the rabbit, and a
getWeight method. The constructor for the
Rabbit class takes the rabbit’s name and the
rabbit’s weight as arguments. A rabbit can be cooked.
Add a class EuropeanRabbit to your program.
European rabbit is a species of rabbit. The
EuropeanRabbitclass has two constructors: the
first constructor takes the European rabbit’s name and the European
rabbit’s weight as arguments; the second constructor only takes the
European rabbit’s name as argument and always uses
2.0 as the European rabbit’s weight. The second
constructor must use the first constructor.
Add a class LapinSautéChasseur to your program.
Lapin sauté chasseur is a kind of European rabbit. The constructor
for the LapinSautéChasseur class takes no
argument. Lapin sauté chasseur is always named
"Delicious" and has a weight of 0.5.
Add a class FrankTheRabbit to your program. Frank
The Rabbit is a kind of rabbit. The constructor for
theFrankTheRabbit class takes no argument. Frank
The Rabbit is always named "Frank", has a weight
of 100.0, and cannot be cooked.
Add a class Start to your program to test all your
classes.
Question 2
Add a class CastIronPot to your program with the
following UML diagram:
+---------------------------------+
| CastIronPot |
+---------------------------------+
| - rabbit: Rabbit |
+---------------------------------+
| + CastIronPot(Rabbit rabbit) |
| + getRabbit(): Rabbit |
| + testCastIronPot(): void |(this method is
static)
+---------------------------------+
In the testCastIronPot method, create a lapin
sauté chasseur called lsc1, then create a cast
iron pot with this lapin sauté chasseur in it. Then get the lapin
sauté chasseur from the cast iron pot and store it into a local
variable called lsc2 of type
LapinSautéChasseur. Use the == operator to check
that lsc1 and lsc2 are the same
lapin sauté chasseur.

The market consensus is that Analog Electronic Corporation has an ROE of 9% and a beta of 1.25. It plans to maintain indefinitely its traditional plowback ratio of 2/3. This year's earnings were $3 per share. The annual dividend was just paid. The consensus estimate of the coming year's market return is 14%, and T-bills currently offer a 6% return.
c. Calculate the present value of growth
opportunities. (Negative amount should be indicated by a
minus sign. Do not round intermediate calculations. Round your
answer to 2 decimal places.)
d. Suppose your research convinces you Analog will announce momentarily that it will immediately reduce its plowback ratio to 1/3. Find the intrinsic value of the stock. (Do not round intermediate calculations. Round your answer to 2 decimal places.)

An oil-drilling company must choose between two mutually exclusive extraction projects, and each requires an initial outlay at t = 0 of $12.6 million. Under Plan A, all the oil would be extracted in 1 year, producing a cash flow at t = 1 of $15.12 million. Under Plan B, cash flows would be $2.2389 million per year for 20 years. The firm's WACC is 11%.
Construct NPV profiles for Plans A and B. Enter your answers in millions. For example, an answer of $10,550,000 should be entered as 10.55. If an amount is zero, enter "0". Negative values, if any, should be indicated by a minus sign. Do not round intermediate calculations. Round your answers to two decimal places.

Find the crossover rate. Do not round intermediate calculations. Round your answer to two decimal places.

Is it logical to assume that the firm would take on all available independent, average-risk projects with returns greater than 11%?
-Select-Yes/ No
If all available projects with returns greater than 11% have been undertaken, does this mean that cash flows from past investments have an opportunity cost of only 11%, because all the company can do with these cash flows is to replace money that has a cost of 11%?
-Select-Yes/ No
Does this imply that the WACC is the correct reinvestment rate assumption for a project's cash flows?
-Select-Yes/ No
