This is for a java program.

Payroll System Using Inheritance and Polymorphism

1. Implement an interface called EmployeeInfo with the following constant variables:

2. Implement an abstract class Employee with the following requirements:

Attributes

last name (String)

first name (String)

mutators and accessors

abstract method monthlyEarning that returns the monthly earning.

3. Implement a class called Staff extending from the class Employee with the following requirements:

Attribute

A study compared three display panels used by air traffic controllers. Each display panel was tested for four different simulated emergency conditions. Twenty-four highly trained air traffic controllers were used in the study. Two controllers were randomly assigned to each display panel-emergency condition combination. The time (in seconds) required to stabilize the emergency condition was recorded. The following table gives the resulting data and the MINITAB output of a two-way ANOVA of the data.

Figure 12.12  

(a) Interpret the interaction plot in the above table. Then test for interaction with α = .05.

(b) Test the significance of display panel effects with α = .05.

F = 43.73, p-value = .0000;   (Click to select)   do not reject   reject  H₀

(c) Test the significance of emergency condition effects with α = .05.

F = 148.31, p-value = .0000;   (Click to select)   do not reject   reject  H₀

(d) Make pairwise comparisons of display panels A, B , and C by using Tukey simultaneous 95 percent confidence intervals. (Round your answers to 2 decimal places. Negative amounts should be indicated by a minus sign.)

(e) Make pairwise comparisons of emergency conditions 1, 2, 3, and 4 by using Tukey simultaneous 95 percent confidence intervals. (Round your answers to 2 decimal places. Negative amounts should be indicated by a minus sign.)

(f) Which display panel minimizes the time required to stabilize an emergency condition? Does your answer depend on the emergency condition? Why?

(g) Calculate a 95 percent (individual) confidence interval for the mean time required to stabilize emergency condition 4 using display panel B. (Round your answers to 2 decimal places.)

Programming language is python 3

For this project, you will import the json module.

Write a class named NeighborhoodPets that has methods for adding a pet, deleting a pet, searching for the owner of a pet, saving data to a JSON file, loading data from a JSON file, and getting a set of all pet species. It will only be loading JSON files that it has previously created, so the internal organization of the data is up to you.

• The init method initializes all the data members, which must all be private.
• The add_pet method takes as parameters the name of the pet, the species of the pet, and the name of the pet's owner. If a pet has the same name as a pet that has already been added, then the function should not add the new pet.
• The delete_pet method takes as a parameter the name of the pet and deletes that pet.
• The get_owner method takes as a parameter the name of the pet and returns the name of its owner.
• The save_as_json method takes as a parameter the name of the file and saves it in JSON format with that name. You can assume the extension (if any) will be part of the provided name. You can organize your JSON file however you want.
• The read_json method takes as a parameter the name of the file to read and loads that file. This will replace all of the pets currently in memory.
• The get_all_species method takes no parameters and returns a set of the species of all pets.

For example, your class could be used like this:

np = NeighborhoodPets()
np.add_pet("Fluffy", "gila monster", "Oksana")
np.add_pet("Tiny", "stegasaurus", "Rachel")
np.add_pet("Spot", "zebra", "Farrokh")
np.save_as_json("pets.json")
np.delete_pet("Tiny")
spot_owner = np.get_owner("Spot")
np.read_json("other_pets.json")  # where other_pets.json is a file it saved in some previous session
species_set = np.get_all_species()

If you implement a Pet class (which is a natural option, but not required), then when you save it, you'll want to translate the information into one of the built-in object types the json module recognizes, and translate it back the other way when you read it.

The file must be named: NeighborhoodPets.py

In Casino Las Vegas, the accounts payable clerk Mr. Alexi Lalas discovered a flaw in the accounting system (accounting software used for general ledger), the accounts payable clerk discovered that he was able to change the names, address and phone numbers of the Casino’s vendors in the computer system to his name or to any other name, there were no evident access controls to the suppliers ( vendors) master file. He would create false invoices and then create a check for the same false invoice. The name on the check would be changed to the name of the employee or any other beneficiary not related to the transaction. After the check was printed, the name in the system could then be changed back to the appropriate vendor. The check register (listing that usually shows listing of checks by date, name and amount) is used by other employees in other departments for many reasons. The fraudulent employee had authorization to sign checks under $1,000. By writing small checks over a period of time, he was able to defraud the company for more than $100,000 over the years of his employment. This fraud was caught by accident. An employee of another department was looking through the vendor list and the check register on her computer after the fraudulent employee had changed the vendor name to his name. A few entries later, the vendor name changed again to the true name of the vendor. She wondered how this could occur and asked her supervisor for an explanation. Soon after, the company’s management hired an independent fraud investigator, after further investigation and inquiries, the fraudulent employee was caught and an admission was received to proceed with the next stage. Check Register Image Inspect the check register and list your notifications with your professional findings and analysis What kind of fraud being committed in this case?, explain how such scheme is possible How could this fraud have been prevented? What actions should be taken against the fraudster(s) and why?

Problem 2: Functions that give answers

Define and complete the functions described below.

The functions are called in the code at the very bottom. So you should be
able simply to run the script to test that your functions work as expected.
'''

'''
* function name: get_name
* parameters: none
* returns: string
* operation:
Here, I just want you to return YOUR name. The expected output below assumes
that your name is Paul. Of course, replace this with the real article.
* expected output:

# JUST RETURNS THE NAME...TO VIEW IT YOU CAN PRINT IT AS BELOW
>>> print(get_name())
Paul

'''

'''
* function name: get_full_name
* parameters: fname (string)
lname (string)
first_last (boolean)
* returns: string
* operation:
Return (again, NOT print) the full name based on the first and last names
passed in as arguments. The first_last argument will be True if you should
return the name as <fname lname> and False if you shoudl return the name
as <lname, fname>.
* expected output:

# AGAIN JUST RETURNS THE NAME...TO VIEW IT YOU CAN PRINT IT AS BELOW
>>> print(get_full_name("Paul","York",True))
Paul York
>>> print(get_full_name("Paul","York",False))
York, Paul

'''

'''
* function name: get_circle_area
* parameters: radius (float)
* returns: float
* operation:
Return the area of a circle with the given radius. Use 3.14 as Pi. And Google if for
some reason you've forgotten how to get the area of a circle.
* expected output:

# YET AGAIN JUST RETURNS THE VALUE
>>> print(get_circle_area(5.0))
78.5
>>> print(get_circle_area(2.5))
19.625

In an experiment to determine the effect of ambient temperature on the emissions of oxides of nitrogen of diesel trucks, ten trucks were run at temperatures of 40°F and 80°F. The emissions, in parts per billion, are presented in the following table.

Test the claim that there is a significant difference in mean emissions between the two temperatures. Use       α = 0.05

An outcome in the cancer experiment is measured by a test for the presence of cells that trigger an immune response in the body and so may help fight cancer. Here are the data of 11 subjects: counts of active cells per 100,000 cells before and after infusion of thee modified cells. The difference ( after minus before) is the response variable.

a). Do the data give an evidence that the count of active cells is higher after treatment ?
