Carefully read the information below, and then do three things with the data. (1) Make two columns (one for costs and the other for benefits) and place each piece of information in the correct column. (2) Prioritize each list, from most important to least important. (3) Write a three-paragraph analysis. Paragraphs one and two should explain why you feel the top two costs and top two benefits are the most important. Finally, paragraph three is your analysis, based on your interpretation of all the facts listed below, explain whether you believe we should pay donors for organs or not. The paper should be typed and no more than one page in length. 1. Under the current system, roughly 30 Americans die every day waiting for an organ transplant. This number would drop significantly if a price rationing system were adopted. 2. Some people are concerned that if we pay donors it will reduce altruism and replace it with greed. 3. Even worse, several studies suggest that paying for donations may actually reduce the incentive for people to choose to be organ donors after death. 4. Payments for organs will help families of the donors pay for burial costs and other death related expenses. 5. The group “Taxpayer Protection” claims that if more organs were available, the government would spend even more money on Medicare funded organ transplants, thus increasing the national debt. 6. However, at studies have shown that organ transplants can be much cheaper than terminal medical care (taking care of patients as they slowly die from lack of a transplant) as long as the patients live at least three years after the surgery. 7. Minorities often wait longer for transplants because fewer minorities donate their organs so there are not as many close matches. Price rationing could help alleviate this problem, as more organs should be available, thus increasing the chances for a close match. 8. Some people are concerned that creating a market for organs might lead to people being killed to harvest their organs to be sold to others in need. 9. A group of religious leaders is concerned about coma patients. They fear that if families of coma patients know they can make money from the sale of the organs they might be more inclined to “pull the plug”. 10. Some people are very concerned that price rationing of organs could benefit the rich at the expense of the poor. 11. If the market is able to eliminate the shortage of organs in the U.S., hospitals could treat patients from all over the world and save more lives

Fairfax Pizza is evaluating a project that would require an initial investment in equipment of 200,000 dollars and that is expected to last for 6 years. MACRS depreciation would be used where the depreciation rates in years 1, 2, 3, and 4 are 40 percent, 33 percent, 19 percent, and 8 percent, respectively. For each year of the project, Fairfax Pizza expects relevant, incremental annual revenue associated with the project to be 346,000 dollars and relevant, incremental annual costs associated with the project to be 314,000 dollars. The tax rate is 50 percent. What is (X plus Y) if X is the relevant operating cash flow (OCF) associated with the project expected in year 1 of the project and Y is the relevant OCF associated with the project expected in year 4 of the project?

Calculate Payroll

Breakin Away Company has three employees-a consultant, a computer programmer, and an administrator. The following payroll information is available for each employee:

	Consultant		Computer Programmer		Administrator
Regular earnings rate	$2,410 per week		$30 per hour		$48 per hour
Overtime earnings rate	Not applicable		1.5 times hourly rate		2 times hourly rate
Number of withholding allowances	3		2		1

For the current pay period, the computer programmer worked 60 hours and the administrator worked 50 hours. The federal income tax withheld for all three employees, who are single, can be determined by adding $356.90 to 28% of the difference between the employee's amount subject to withholding and $1,796.00. Assume further that the social security tax rate was 6%, the Medicare tax rate was 1.5%, and one withholding allowance is $70.

Determine the gross pay and the net pay for each of the three employees for the current pay period. Assume the normal working hours in a week are 40 hours. If required, round your answers to two decimal places.

3. Write a function named "countNonAlpha" that accepts a string. It will return the number of non-alphabet characters (excluding blanks) in the string.
For example, if the string is "Hello, World!", it will return 2 for ',' and '!" in the string.

4. Write a function named "deleteZeros" that takes two arguments:
a. an array of integer values;
b. an integer for the number of elements in the array;
The function will return the number of zeros that it has deleted from the array
The function should shift the contents of each element in the array whenever a zero
element is deleted
For example, if the array is defined as
int numList[] = {10, 0, 20, 30, 40, 0, 50};
The function will return 2 and shift to make the array to contain
10 20 30 40 50

5. Write a function named "reverseCase" that takes only one argument of a C-string (an array of characters that terminates with a NULL ('\0') character).
The function will change all lower cases to upper case and vice versa in that given
C-string. If the character is not an alphabet, it will be unchanged.
The function will return the number of letters that it has changed.
For example, if the array is defined as
char greeting[] = " Hello, World! ";
It will return 10 and change the array to contain
hEELO, wORLD!

Using excel and the data in chapter 14 data set 2, complete the analysis and interpret the results. It is a 2 x 3 experiment: There are two levels of severity, where the Level 1 is severe and Level 2 is mild, and there are three levels of treatment, where Level 1 is Drug #1, Level 2 is Drug #2, and Level 3 is Placebo. This is an ANOVA with replication because each participant received all three levels of treatment, which are represented by the columns of data; severity is represented by the rows.

Java program.

Need to create a class names gradesgraph which will represent the GradesGraphtest program.

Assignment

Create a class GradesGraph that represents a grade distribution for a given course. Write methods to perform the following tasks:

• Set the number of each of the letter grades A, B, C, D, and F.

• Read the number of each of the letter grades A, B, C, D, and F.

• Return the total number of grades.

• Return the percentage of each letter grade as a whole number between 0 and 100, inclusive.

• Draw a bar graph of the grade distribution.

The graph will have five bars, one per grade. Each bar can be a horizontal row of asterisks, such that the number of asterisks in a row is proportionate to the percentage of grades in each category. Let one asterisk represent 2 percent, so 50 asterisks correspond to 100 percent. Mark the horizontal axis at 10 percent increments from 0 to 100 percent, and label each line with its letter grade.

For example, if the grades are 1 A, 4 Bs, 6 Cs, 2 Ds, and 1 F, the total number of grades is 14, the percentage of As is 7, the percentage of Bs is 29, the percentage of Cs is 43, the percentage of Ds is 14, and the percentage of Fs is 7. The A row would contain 4 asterisks (7 percent of 50 rounded to the nearest integer), the B row 14, the C row 21, the D row 7, and the F row 4.

We wish to predict the salary for baseball players (y) using the variables RBI (x1) and HR (x2), then we use a regression equation of the form ˆy=b0+b1x1+b2x2.

• HR - Home runs - hits on which the batter successfully touched all four bases, without the contribution of a fielding error.
• RBI - Run batted in - number of runners who scored due to a batters' action, except when batter grounded into double play or reached on an error
• Salary is in millions of dollars.

ˆy= ______ + _____ x1 + ______ x2

b) Use the multiple linear regression equation to predict the salary for a baseball player with an RBI of 31 and HR of 20. Round your answer to 1 decimal place, do not convert numbers to dollars.
      ________ millions of dollars

c) Holding all other variables constant, what is the correct interpretation of the coefficient b1=0.111 in the multiple linear regression equation?

• For each HR, a baseball player's predicted salary increases by 0.111 million dollars.
• For each RBI, a baseball player's predicted salary increases by 0.111 million dollars.
• If the baseball player's salary increases by 0.111 million dollars, then the predicted RBI will increase by one.
• If the baseball player's salary increases by 0.111 million dollars, then the predicted RBI will increase by 0.0371.

d) Holding all other variables constant, what is the correct interpretation of the coefficient b2=0.0371 in the multiple linear regression equation?

• If the baseball player's salary increases by 0.0371 million dollars, then the predicted HR will increase by one.
• If the baseball player's salary increases by 0.0371 million dollars, then the predicted HR will increase by 0.111.
• For each RBI, a baseball player's predicted salary increases by 0.0371 million dollars.
