Overview
For the purposes of this assignment, imagine that you are a systems architect at a medium-sized publishing company with 130 employees. The company primarily publishes books, both in print and online. It also produces other kinds of content, such as audiobooks, interactive reading material, and magazines. Your leadership has decided that it is time to either upgrade the current OS or adopt a new one (e.g., Windows, Linux, macOS).
As the systems architect, you have the responsibility to determine which OS the company should implement for each department. There are many aspects to consider when making this decision, including what existing applications are used by employees on a frequent basis, cost, functionality provided, performance, vendor support, and so on. To determine which OS should be implemented, you need to complete a site survey first. Later, the site survey can be used to help you make a decision as to which operating systems to implement based on what is currently used in the department. For this activity, you will conduct a site survey. This is also a step that you will need to take when you submit Project One in Module Four. The feedback that you receive after submitting this activity should be implemented as you craft your Project One submission.
Prompt
Complete a Site Survey: A site survey compares the three different operating systems that the company is planning to implement. To complete this task, use the Project One Site Survey Template linked in the Supporting Materials area. Specifically, you must address the following rubric criteria:
Operating Systems: Acknowledge what OSes are already used in your site survey. The type of OS already used and how many employees are using it can influence your decision making.
Server: Determine whether the desktops are on a hardware or cloud-based server.
Although not required in this portion of the project, you may want to think about whether or not the server should be changed. This change could be recommended in your proposal.
Standard Hardware for Operating System Types: Determine the minimum required hardware. This could include desktop and server.
Network Connection: Determine whether the network is wired or wireless.
You will want to think about whether or not the network connection should be changed. This change could be recommended in your proposal.
Applications: Identify what software applications need to be supported by the OS. Your survey of what applications desktop users use most frequently will influence your decision making, as some applications are not supported by certain OSes.
Supporting Materials
The following resources support your work on the project:
Reading: Organizational Needs
This document will provide you with context on the company’s needs and industry best practices. As you review this document, you will learn about what the company currently uses when it comes to hardware and software. Learning about the organization’s needs can help you make an informed decision on which OS to implement.
Template: Site Survey Template
Use this template to compare the operating systems that the company can implement for its employees who use desktops. For this activity, do not complete the portion of this template that includes the proposal.
What to Submit
Site Survey: Your submission for this milestone should be the completed first six sections of the Site Survey Template in Word (.docx) format. Do not complete the last two sections of this template; you will complete these for Project One.

The questions is in this word document. some questions require you to give a java program others require you to explain the java programm that has been given. you either use Note pad++ to help you or Eclipse IDE but ALL answers is going on this document. i can also extend the time if needed just let me know.

I need you to help me find a topic about doing research and finding a solution to some of Machine learning’s most hard-to-solve issues. I need help coming up with a brief thesis before we start the project. 

Submit all your answers in attached document. Case Studies can be found on page 657 (Chapter 20) of your textbook. You can also access the online version of the case study by clicking on the link associated with the case study.
1. Diet and Health (DH) Case Study (15 Points)
What percentage of people on the AHA diet had some sort of illness or death?
What is the probability that if you randomly selected a person on the AHA diet, he or she would have some sort of illness or death?
If 3 people on the AHA diet are chosen at random, what is the probability that they will all be healthy? 2. Diet and Health (DH) Case Study (32 Points)
What percentage of people on the Mediterranean diet had some sort of illness or death?
What is the probability that if you randomly selected a person on the Mediterranean diet, he or she would have some sort of illness or death?
What is the probability that if you randomly selected a person on the Mediterranean diet, he or she would have cancer?
If you randomly select five people from the Mediterranean diet, what is the probability that they would all be healthy? 3. A refrigerator contains 6 apples, 5 oranges, 10 bananas, 3 pears, 7 peaches, 11 plums, and 2 mangos. (15 Points)
Imagine you stick your hand in this refrigerator and pull out a piece of fruit at random. What is the probability that you will pull out a pear?
Imagine now that you put your hand in the refrigerator and pull out a piece of fruit. You decide you do not want to eat that fruit so you put it back into the refrigerator and pull out another piece of fruit. What is the probability that the first piece of fruit you pull out is a banana and the second piece you pull out is an apple?
What is the probability that you stick your hand in the refrigerator one time and pull out a mango or an orange? 4. Angry Moods (AM) Case Study (18 Points)
For this problem, use the Anger Expression (AE) scores. Compute the mean and standard deviation.
Then, compute what the 25th, 50th and 75th percentiles would be if the distribution were normal.
Compare the estimates to the actual 25th, 50th, and 75th percentiles. 5. Physicians’ Reactions (PR) case study (30 points) For this problem, use the time spent with the overweight patients. Compute the mean and standard deviation of this distribution.
What is the probability that if you chose an overweight participant at random, the doctor would have spent 31 minutes or longer with this person?
Now assume this distribution is normal (and has the same mean and standard deviation). Now what is the probability that if you chose an overweight participant at random, the doctor would have spent 31 minutes or longer with this person? 6. Suppose that combined verbal and math SAT scores follow a normal distribution with mean 896 and standard deviation 174. Suppose further that Peter finds out that he scored in the top 3% of SAT scores. Determine how high Peter’s score must have been. (10 Points)
7. Heights of adult women in the United States are normally distributed with a population mean of μ= 63.5 inches and a population standard deviation of σ = 2.5. A medical re- searcher is planning to select a large random sample of adult women to participate in a future study. What is the standard value, or z-value, for an adult woman who has a height of 68.5 inches? (10 Points)
8. An automobile manufacturer introduces a new model that averages 27 miles per gallon in the city. A person who plans to purchase one of these new cars wrote the manufacturer for the details of the tests and found out that the standard deviation is 3 miles per gallon. Assume that in-city mileage is approximately normally distributed. (20 Points)
What is the probability that the person will purchase a car that averages less than 20 miles per gallon for in-city driving?
What is the probability that the person will purchase a car that averages between 25 and 29 miles per gallon for in-city driving?

Projects Overview
In this course, you will be completing projects that simulate Capture the Flag (CTF) activities. CTFs are information security competitions where individuals or teams apply real-world hacking techniques to infiltrate a system, find intentionally placed vulnerabilities, and exploit them to locate the “flag,” a string of code that proves they were able to exploit the flaw (GitHub, n.d.) In this scenario, you have been hired as a Security Operations Center (SOC) Analyst Blue Teamer at Centralia Technology, a cybersecurity services company helping organizations secure their digital assets. Your manager is putting together teams for a CTF competition coming up in a few months. Centralia Technology wants its own teams to compete with the best in the country. The CTF activities are designed to create a collaborative team learning environment. Your manager wants everyone to participate in a simulated CTF event individually. Following that, you will be put into teams of diverse skill sets to work together to analyze and solve challenges. Near the end of the course, you will present your solutions to share and exchange knowledge with everyone in the company (class). You will be completing these activities: Project 1: Capture the Flag Write-Up (Week 3) – This is an individual project to see what techniques, tools, websites, or other resources you can use to help solve challenges. You will identify one or two challenges you didn’t attempt or complete and identify the areas you had trouble with. You will correctly answer 10 questions from the in-house CTF quiz bank and submit your company survey.
