Use C++ please

You will be building a linked list. Make sure to keep track of both the head and tail nodes.

(1) Create three files to submit.

• PlaylistNode.h - Class declaration
• PlaylistNode.cpp - Class definition
• main.cpp - main() function

Build the PlaylistNode class per the following specifications. Note: Some functions can initially be function stubs (empty functions), to be completed in later steps.

• Default constructor (1 pt)
• Parameterized constructor (1 pt)
• Public member functions
  • InsertAfter() - Mutator (1 pt)
  • SetNext() - Mutator (1 pt)
  • GetID() - Accessor
  • GetSongName() - Accessor
  • GetArtistName() - Accessor
  • GetSongLength() - Accessor
  • GetNext() - Accessor
  • PrintPlaylistNode()
• Private data members
  • string uniqueID - Initialized to "none" in default constructor
  • string songName - Initialized to "none" in default constructor
  • string artistName - Initialized to "none" in default constructor
  • int songLength - Initialized to 0 in default constructor
  • PlaylistNode* nextNodePtr - Initialized to 0 in default constructor

Ex. of PrintPlaylistNode output:

Unique ID: S123
Song Name: Peg
Artist Name: Steely Dan
Song Length (in seconds): 237

(2) In main(), prompt the user for the title of the playlist. (1 pt)

Ex:

Enter playlist's title:
JAMZ 

(3) Implement the PrintMenu() function. PrintMenu() takes the playlist title as a parameter and outputs a menu of options to manipulate the playlist. Each option is represented by a single character. Build and output the menu within the function.

If an invalid character is entered, continue to prompt for a valid choice. Hint: Implement Quit before implementing other options. Call PrintMenu() in the main() function. Continue to execute the menu until the user enters q to Quit. (3 pts)

Ex:

JAMZ PLAYLIST MENU
a - Add song
d - Remove song
c - Change position of song
s - Output songs by specific artist
t - Output total time of playlist (in seconds)
o - Output full playlist
q - Quit

Choose an option:

In this exercise, you will create a basic data management system for students in the Department of Computer Science and Information Technology using the linked list.

You must write two classes – Student class attached, and StudentChart.

Student class consists of student data. StudentChart class contains a linked list of all students in the department.

For this purpose, you must fulfill the following interfaces (note - fields of the objects should be marked as private).

Class: Student chart

Class of Student Chart contains data for all students stored in a linked list. The way to add a student to the list by method addStudent only to the front of the list. At the beginning the student list is empty, the number of students enrolled in the Department is 0. Think what would be the fields of this class, so that you can know much information at any one time.

Constructors:

Methods:

It is recommended to write tester to present all the methods of the class and to check that they actually work.

The student class :

public class Student {
   private String name;// student name
   private long id; // student identity number
   private int [] grades = new int[5]; // list of student courses grades
   
   //costructor that initialize name and id
   public Student(String name, long id){
       String n = name.toUpperCase();
       name = name.replace(name.charAt(0), n.charAt(0));

Many fast-food restaurants use automatic soft-drink dispensing machines that fill cups once an order is placed at a drive-through window. A regional manager for a fast-food chain wants to determine if the machines in her region are dispensing the same amount of product. She samples four different machines and measures a random sample of 16-ounce drinks from each machine. Here is the data she collects (in ounces):

a) “Number of ounces” is a quantitative variable. Is it discrete or continuous?

b) “Number of ounces” is what level of measurement?

c) Is this a designed experiment or an observational study? Briefly explain.

d) At the 5% Level of Significance, determine whether or not the data indicate that the mean amount dispensed from the machines is not the same, by doing each of the following:

1) Write the Hypotheses.

2) Use your calculator to do a one-way ANOVA test. Explain in some detail how the results of the test lead you to reject or not reject the null hypothesis.

3) Write a formal conclusion.

e) Using the language of our textbook on bias (way back in Section 1.5), name at least one type of bias that might be present in this research. Briefly explain.

USING R TO ANSWER QUESTION: Performance Tires plans to engage in direct mail advertising. It is currently in negotiations to purchase a mailing list of the names of people who bought sports cars within the last three years. The owner of the mailing list claims that sales generated by contacting names on the list will more than pay for the cost of using the list. (Typically, a company will not sell its list of contacts, but rather provides the mailing services. For example, the owner of the list would handle addressing and mailing catalogs.) Before it is willing to pay the asking price of $3 per name, the company obtains a sample of 225 names and addresses from the list in order to run a small experiment. It sends a promotional mailing to each of these customers. The data for this exercise show the gross dollar value of the orders produced by this experimental mailing. The company makes a profit of 20% of the gross dollar value of a sale. For example, an order for $100 produces $20 in profit.

c. Describe the appropriate hypotheses and type of test to use. Choose (and justify) an alpha-level for the test. Check whether the sample size condition and the random sample condition are met.

d. Summarize the results of the sample mailing. Use a histogram and appropriate numerical statistics.

e. Summarize the results of the test. Make a recommendation to the management of Performance Tires

In a study examining psychological and organization efforts of pets in the workplace, Wells and Perrine (2001) found that employees believed pets reduced stress and brought positive benefits to the environment. Suppose another researcher, Dr. D, believes that the presence of pets will reduce speech anxiety in oral communication classes. To test this theory, participants were recruited from oral communication classes and randomly assigned to deliver a 10- minute persuasive speech either with or without a small older yet quiet dog resting near the podium. All speeches were videotaped, and trained observers scored the number of anxiety behaviors, such as shaking hands, wobbly legs, and cracking voice. Participants also completed a speech anxiety questionnaire when they finished their speech. As Dr. D expected, participants reported less anxiety when the dog was present than participants in the control condition.

1.Identify the null and research hypotheses for this experiment?

2.Identify the independent variable and state the different levels?

3.Identify the dependent variable?

4.What is the experimental designs?

5.Name several extraneous variables that should be controlled?

6.Evaluate this study for experimenter bias and demand characteristics?

7.If the researcher examined differences in anxiety reduction between female and male participants, what kind of research design would this be?

8.If the difference in anxiety level between the experimental and control groups are due to chance, explain to the researcher why the results would change?

9.If true anxiety differences existed between the two experimental conditions, but they were not detected, what kind of error occurred?
