An automobile manufacturer claims that its cars average more than 410 miles per tankful (mpt).
As evidence, they cite an experiment in which 17 cars were driven for one tankful each and
averaged 420 mpt. Assume σ = 14 is known.

a. Is the claim valid? Test at the 5 percent level of significance.

b. How high could they have claimed the mpt to be? That is, based on this experiment, what is the maximum value for µ which would have been rejected as an hypothesized value?

c. What is the power of the test in part (a) when the true value of µ is 420 mpt? (Hint: Your rejection region for part (a) was stated in terms of comparing Zobs with a cut-off point on the Z distribution. Find the corresponding x̅cut-off and restate your rejection region in
terms of comparing the observed x̅value with the x̅cut-off. Then assume H1 is true (i.e. µ
= 420 mpt) and find the probability that x̅is in the rejection region.)

Robert Millikan is famous for his experiment which demonstrated that electric charge is discrete, or quantized. His experiment involved measuring the terminal velocities of tiny charged drops of oil in air between two plates with a known voltage applied. He timed hundreds of them traveling both up and down in order to mathematically rule out the effects of gravity and drag, since he had no way of measuring mass or diameter. His results showed that charge comes only in integer multiples of 1.6 10 19C. This is called the elementary charge. It is the charge on both electrons, negative, and protons, positive.
1. a. Where does charge excess charge reside on an object? Why?
b. Where is electric charge more concentrated on irregularly shaped objects?
c. How do lightning rods work?
d. Why does a stream of water bend toward a charged object?
e. What are the three methods of charging an object?

Even if the double slit experiment gives interesting (weird) results, it only concludes that each photon interacts with itself after passing the two slits. I have been thinking about a different experimental setup, where you have two well defined light sources (with specific wave lengths and phase) but no slits. And now to my questions: Has anyone ever done such an experiment, and will there be an interference pattern on the wall?

If the answer to the second question is "no", light can not be a true wave - it only has some wavelike properties. But if it is "yes", things become much more interesting.

If there is an interference pattern on the wall, there has to be an interference pattern even if both light sources are emitting single photons at random, but as seldom as, say, once per minute. That in turn would mean that the photons know about each other, even if they are separated in time with several seconds, and the light sources are independent (not entangled).

Consider the Monty Hall problem.Verify the results using by writing a computer program that estimates the probabilities of winning for different strategies by simulating it.

1. First, write a code that randomly sets the prize behind one of three doors and you also randomly select one of the doors. You win if the the door you selected has the prize (Here, we are simulating ’stick to the initial door’ strategy). Repeat this experiment 100 times and compute the average number of wins.

2. Next, try simulating the switching strategy. Find the door the host will open and change your initial door with the door not opened by the host. Also repeat this experiment 100 times and compute the average number of wins. If you did everything right, the first code should yield the probability of winning as ≈ 1/3 and the second code should yield ≈ 2/3. You can use any programming language you want (MATLAB, Python etc.)

CASE STUDY 36.1 Patient With a Transplant

Brief Patient History

Mr. V is a 42-year-old man with chronic viral hepatitis C. He has a Model for End-Stage Liver Disease (MELD) score greater than 25. Mr. V is in acute fulminant liver failure and is on the waiting list to receive a liver transplant. Mr. V was hospitalized 2 weeks ago with ascites, hepatorenal syndrome, and hepatic encephalopathy. He has been treated with diuretics, antibiotics, and laxatives. Before transplantation, he remained in the intermediate care unit and was not intubated. He is now undergoing liver transplantation.

Hero Manufacturing has 8.4 million shares of common stock outstanding. The current share price is $78...

Hero Manufacturing has 8.4 million shares of common stock outstanding. The current share price is $78 and the book value per share is $5. The company also has two bond issues outstanding. The first bond issue has a face value of $65 million, a coupon rate of 6.5 percent and sells for 108.3 percent of par. The second issue has a face value of $50.3 million, a coupon rate of 7.7 percent and sells for 112.1 percent of par. The first issue matures in 9 years, the second in 27 years.

Suppose the company’s stock has a beta of 1.3. The risk-free rate is 2.7 percent and the market risk premium is 6.8 percent. Assume that the overall cost of debt is the weighted average implied by the two outstanding debt issues. Both bonds make semiannual payments. The tax rate is 21 percent. What is the company’s WACC?

****Please show how to solve with financial calculator where applicable****

This is the solve provided but there is no explanation as how the YTM was calculated:

The market value of equity is the share price times the number of shares, so:
S = 8,400,000($78)
S = $655,200,000

Using the relationship that the total market value of debt is the price quote times the par value of the bond, we find the market value of debt is:

B = 1.083($65,000,000) + 1.121($50,300,000)
B = $126,781,300
This makes the total market value of the company:
V = $655,200,000 + 126,781,300
V = $781,981,300
And the market value weights of equity and debt are:
S/V = $655,200,000/$781,981,300
S/V = .8379
B/V = 1 – S/V = .1621

Next, we will find the cost of equity for the company. The information provided allows us to solve for the cost of equity using the CAPM, so:

RS = .027 + 1.3(.068)

RS = .1154, or 11.54%

Next, we need to find the YTM on both bond issues. Doing so, we find:

P1 = $1,083 = $32.50(PVIFAR%,18) + $1,000(PVIFR%,18)
R = 2.664%
YTM = 2.664% × 2
YTM = 5.33%
P2 = $1,121 = $38.50(PVIFAR%,54) + $1,000(PVIFR%,54)
R = 3.361%
YTM = 3.361% × 2
YTM = 6.72%

To find the weighted average aftertax cost of debt, we need the weight of each bond as a percentage of the total debt. We find:

XB1 = 1.083($65,000,000)/$126,781,300
XB1 = .555
XB2 = 1.121($50,300,000)/$126,781,300
XB2 = .445

Now we can multiply the weighted average cost of debt times one minus the tax rate to find the weighted average aftertax cost of debt. This gives us:

RB = (1 – .21)[(.555)(.0533) + (.445)(.0672)]
RB = .0470, or 4.70%

Using these costs and the weight of debt we calculated earlier, the WACC is:

RWACC = .8379(.1154) + .1621(.0470)
RWACC = .1043, or 10.43%

INPUT FILE INTO ARRAY. CHECKING FOR COMMAS AND SUCH. PLEASE READ CAREFULLY.

void readFile(Candidate candidates[]) – reads the elections.txt file, fills the candidates[] array. Hint: use substr() and find() functions. Set Score to 0.


void List(Candidate candidates[]) – prints the array of Candidate structs. One candidate per one line, include all fields. Use setw() to display nice looking list.


void displayCandidate(Candidate candidates[]) – prints the complete information about the candidate

.
Candidate First(Candidate candidates[]) – returns single struct element: candidate with highest score


Candidate Last(Candidate candidates[]) – returns single struct element: candidate with lowest score


void Votes(Candidate candidates[]) – function sorts the candidates[] array by number of votes, the order in candidates[] array is replaced


void Scores(Candidate candidates[]) – calculates the percentage score for each candidate. Use the following formula: ??????=(CandidateVotes)/(sum of votes)*100%

Correct line for the reference: F=John,L=Smith,V=3342

The line errors that your program needs to detect, are as follows:

incorrect token / separator, example in line 5: F=Steven,L=JohnV=4429 --- (comma missing) – lines with this error need to be ignored

space in token, example in line 3: F=Hillary,X=Clinton, V=1622 --- lines with this error need to be read, error fixed, data included in your dataset

empty line, example in line 6 – empty lines need to be ignored

Example Textfile

F=Michael,L=John,V=3342

F=Danny,L=Red,V=2003

F=Hillary,L=Clinton, V=1588

F=Albert,L=Lee,V=5332

F=Steven,L=JohnV=4429
