For this task you will examine the experiments of Loftus and Gardner. Describe and analyze each of these experiments. You will prepare two separate analyses; for each analysis, include the following:
A brief summary of the study
A one paragraph explanation of the background in the field leading up to the study, and the reasons the researchers carried out the project.
The significance of the study to the field of psychology
A brief discussion of supportive or contradictory follow-up research findings and subsequent questioning or criticism from others in the field
A summary of at least one recent experiment (within the past two years) that is related to the seminal experiment (Hint: Excellent sources for recent research summaries are the American Psychological Association’s Monitor on Psychology and the Association for Psychological Science).
Your own evaluation of whether the breakthrough experiments of Drs. Gardner and Loftus were examples of genius, the zeitgeist, or some other factor. Use their own autobiographical accounts as well as your analyses of their experiments and personal stories to support your opinion.

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?

b. Find the probability that at least 14 flights are on time.
c. Find the probability that fewer than 14 flights are on time.
d. Find the probability that between 12 and 14 flights are on time.
e. Find the probability that every flight is on time.

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.
Clinical Assessment
Mr. V is admitted to the critical care unit from the operating room after receiving an orthotopic liver transplant. He is intubated and sedated. Mr. V moves all extremities but does not follow commands. He has a nasogastric tube, pulmonary artery catheter, arterial line, urinary catheter, abdominal drain (draining bright red blood), and external biliary drain in place. Continuous renal replacement therapy is in progress.
Diagnostic Procedures
Baseline vital signs include the following: blood pressure of 100/60 mm Hg, heart rate of 118 beats/min (sinus tachycardia), respiratory rate of 20 breaths/min, temperature of 98.3°F, and oxygen saturation of 98%.
Urine output was 75 mL/h and is now 15 mL/h. Central venous pressure is 14 mm Hg, pulmonary artery pressure is 30/16 mm Hg, pulmonary artery occlusion pressure is 18 mm Hg, and intraabdominal pressure is greater than 25 mm Hg.
His current laboratory values include the following:
White blood cell count: 3100 cells/mm3
Hematocrit: 25.3%
Hemoglobin: 8.6 g/dL
Platelet count: 47,000/microliter
Aspartate aminotransferase: 315 units/L
Aminotransferase: 230 units/L
Alkaline phosphatase: 380 units/L

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:

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

Suppose 2017 sales are projected to increase by 25% over 2016 sales. Use the forecasted financial statement method to forecast a balance sheet and income statement for December 31, 2017. The interest rate on all debt is 9%, and cash earns no interest income. Assume that all additional debt in the form of a line of credit is added at the end of the year, which means that you should base the forecasted interest expense on the balance of debt at the beginning of the year. Use the forecasted income statement to determine the addition to retained earnings. Assume that the company was operating at full capacity in 2016, that it cannot sell off any of its fixed assets, and that any required financing will be borrowed as a line of credit. Also, assume that assets, spontaneous liabilities, and operating costs are expected to increase by the same percentage as sales. Determine the additional funds needed. Round your answers to the nearest dollar. Do not round intermediate calculations.
