The project is adapted from the Chapter 4 Case Study dealing with North–South Airline In January 2012, Northern Airlines merged with Southeast Airlines to create the fourth largest U.S. carrier. The new North–South Airline inherited both an aging fleet of Boeing 727-300 aircraft and Stephen Ruth. Stephen was a tough former Secretary of the Navy who stepped in as new president and chairman of the board.

Stephen’s first concern in creating a financially solid company was maintenance costs. It was commonly surmised in the airline industry that maintenance costs rise with the age of the aircraft. He quickly noticed that historically there had been a significant difference in the reported B727-300 maintenance costs (from ATA Form 41s) in both the airframe and the engine areas between Northern Airlines and Southeast Airlines, with Southeast having the newer fleet.

On February 12, 2012, Peg Jones, vice president for operations and maintenance, was called into Stephen’s office and asked to study the issue. Specifically, Stephen wanted to know whether the average fleet age was correlated to direct airframe maintenance costs and whether there was a relationship between average fleet age and direct engine maintenance costs. Peg was to report back by February 26 with the answer, along with quantitative and graphical descriptions of the relationship.

Peg’s first step was to have her staff construct the average age of the Northern and Southeast B727-300 fleets, by quarter, since the introduction of that aircraft to service by each airline in late 1993 and early 1994. The average age of each fleet was calculated by first multiplying the total number of calendar days each aircraft had been in service at the pertinent point in time by the average daily utilization of the respective fleet to determine the total fleet hours flown. The total fleet hours flown was then divided by the number of aircraft in service at that time, giving the age of the “average” aircraft in the fleet.

The average utilization was found by taking the actual total fleet hours flown on September 30, 2011, from Northern and Southeast data, and dividing by the total days in service for all aircraft at that time. The average utilization for Southeast was 8.3 hours per day, and the average utilization for Northern was 8.7 hours per day. Because the available cost data were calculated for each yearly period ending at the end of the first quarter, average fleet age was calculated at the same points in time. The fleet data are shown in the following table.

The project is derived from a case study located at the end of chapter 4 dealing with regression analysis. Please note, however that some of the numbers in the project tables in the text have been changed so students should get their complete instructions from the Project area provided in Getting Started section of the Table of Contents. Students should use the Data Analysis add-on pack from the standard Microsoft Excel software available in every Microsoft Office software since 2007. The project requirements are:  

1. Prepare Excel Data Analysis Regression Tables demonstrating your excellence at determining Northern and Southeast Costs to Average Age. Besides the data tables, copied from the project instructions, four regression models are required each on a separate tab. Place each regression model with supporting data labels, line fit plots, and other required items on a separate worksheet tab.
2. On each worksheet tab (other than the data table tab) include:
   1. a copy of your data entry screen (Use Alt+Print Screen to copy picture of Regression Data Entry from Data Analysis in Excel and paste on correct worksheet tab).
   2. The regression model derived from the data tables.
   3. Line Fit Plot for each Worksheet tab.
   4. Labels of the data included.
   5. Highlight with yellow and label the following four items on each regression model:
      1. Coefficient of determination
      2. Coefficient of correlation or covariance
      3. Slope, and
      4. Beta or intercept
3. Finally prepare a formal response, using Microsoft Word, from Peg Jones’s to Stephen Ruth explaining your numbers and calculations. Which costs are correlated with the average age of the aircraft? What is the slope and beta? Explain the coefficient of determination and covariance. Explain how this information benefits each airline.

Submit your Excel Worksheet with five tabs (data, plus 4 tabs for the regressions) to the assignment drop box. Also include your formal response in a Microsoft Word document. Late work will not be accepted. The Excel worksheet and Word documents must be submitted BEFORE then end of Unit 7. This project is worth 160 points.

Note: Dates and names of airlines and individuals have been changed in this case to maintain confidentiality. The data and issues described here are real.

C++ Question:

we need to read speech from .txt file.

Steve Jobs delivered a touching and inspiring speech at Stanford's 2005 commencement. The transcript of this speech is attached at the end of this homework description. In this homework, you are going to write a program to find out all the unique tokens (or words) used in this speech and their corresponding frequencies, where the frequency of a word w is the total number of times that w appears in the speech. You are required to store such frequency information into a vector and then sort these tokens according to frequency. Please feel free to use existing functions such as strtok() or sstream to identify tokens in this implementation.

Specifically, you are required to include the following elements in your program:

Declare a struct TokenFreq that consists of two data members: (1) string value; and (2) int freq; Obviously, an object of this struct will be used to store a specific token and its frequency. For example, the following object word stores the token "dream" and its frequency 100:

  TokenFreq word;

  word.value="dream";

word.freq=100;

Remember to declare this struct at the beginning of your program and outside any function. A good place would be right after the "using namespace std;" line. This way, all the functions in your program will be able to use this struct to declare variables.

Implement the function vector<TokenFreq> getTokenFreq( string inFile_name); This function reads the specified input file line by line, identifies all the unique tokens in the file and the frequency of each token. It stores all the identified (token, freq) pairs in a vector and returns this vector to the calling function. Don't forget to close the file before exiting the function. In this homework, these tokens are case insensitive. For example, "Hello" and "hello" are considered to be the same token.  

Implement the selection sort algorithm to sort a vector<TokenFreq> in ascending order of token frequency. The pseudo code of the selection algorithm can be found at http://www.algolist.net/Algorithms/Sorting/Selection_sort You can also watch an animation of the sorting process at http://visualgo.net/sorting -->under "select". This function has the following prototype:

void selectionSort( vector<TokenFreq> & tokFreqVector ); This function receives a vector of TokenFreq objects by reference and applies the selections sort algorithm to sort this vector in increasing order of token frequencies.  

Implement the insertion sort algorithm to sort a vector<TokenFreq> in descending order of token frequency. The pseudo code of the selection algorithm can be found at http://www.algolist.net/Algorithms/Sorting/Insertion_sort Use the same link above to watch an animation of this algorithm. This function has the following prototype:

void insertionSort( vector<TokenFreq> & tokFreqVector );  

Implement the void writeToFile( vector<TokenFreq> &tokFreqV, string outFileName); function. This function receives a vector of TokenFreq objects and writes each token and its frequency on a separate line in the specified output file.

Implement the int main() function to contain the following features: (1) asks the enduser of your program to specify the name of the input file, (2) ) call the getTokenFreq() to identify each unique token and its frequency, (3) call your selection sort and insertion sort functions to sort the vector of TokenFreq objects assembled in (2); and (4) call the WriteToFile() function to print out the sorted vectors in two separate files, one in ascending order and the other in descending order.    

Example input and outputs:  

Assume that your input file contains the following paragraph: "And no, I'm not a walking C++ dictionary. I do not keep every technical detail in my head at all times. If I did that, I would be a much poorer programmer. I do keep the main points straight in my head most of the time, and I do know where to find the details when I need them. by Bjarne Stroustrup"

After having called the getTokenFreq() function, you should identify the following list of (token, freq) pairs and store them in a vector (note that the order might be different from yours): {'no,': 1, 'and': 1, 'walking': 1, 'be': 1, 'dictionary.': 1, 'Bjarne': 1, 'all': 1, 'need': 1, 'Stroustrup': 1, 'at': 1, 'times.': 1, 'in': 2, 'programmer.': 1, 'where': 1, 'find': 1, 'that,': 1, 'would': 1, 'when': 1, 'detail': 1, 'time,': 1, 'to': 1, 'much': 1, 'details': 1, 'main': 1, 'do': 3, 'head': 2, 'I': 6, 'C++': 1, 'poorer': 1, 'most': 1, 'every': 1, 'a': 2, 'not': 2, "I'm": 1, 'by': 1, 'And': 1, 'did': 1, 'of': 1, 'straight': 1, 'know': 1, 'keep': 2, 'technical': 1, 'points': 1, 'them.': 1, 'the': 3, 'my': 2, 'If': 1}

After having called the selectionSort() function, the sorted vector of token-freq pairs will contain the following information (again, the tokens of the same frequency might appear in different order from yours) : [('no,', 1), ('and', 1), ('walking', 1), ('be', 1), ('dictionary.', 1), ('Bjarne', 1), ('all', 1), ('need', 1), ('Stroustrup', 1), ('at', 1), ('times.', 1), ('programmer.', 1), ('where', 1), ('find', 1), ('that,', 1), ('would', 1), ('when', 1), ('detail', 1), ('time,', 1), ('to', 1), ('much', 1), ('details', 1), ('main', 1), ('C++', 1), ('poorer', 1), ('most', 1), ('every', 1), ("I'm", 1), ('by', 1), ('And', 1), ('did', 1), ('of', 1), ('straight', 1), ('know', 1), ('technical', 1), ('points', 1), ('them.', 1), ('If', 1), ('in', 2), ('head', 2), ('a', 2), ('not', 2), ('keep', 2), ('my', 2), ('do', 3), ('the', 3), ('I', 6)]

Guidelines for the program:

• All methods listed below must be public and static.
• If your code is using a loop to modify or create a string, you need to use the StringBuilder class from the API.
• Keep the loops simple but also efficient. Remember that you want each loop to do only one "task" while also avoiding unnecessary traversals of the data.
• No additional methods are needed. However, you may write additional private helper methods, but you still need to have efficient and simple algorithms. Do not write helper methods that do a significant number of unnecessary traversals of the data.
• Important: you must not use either break or continue in your code. These two commands are often used to compensate for a poorly designed loop. Likewise, you must not write code that mimics what break does. Instead, re-write your loop so that the loop logic does not need break-type behavior.
• While it may be tempting to hunt through the API to find classes and methods that can shorten your code, you may not do that. The first reason is that this homework is an exercise in writing loops, not in using the API. The second reason is that in a lot of cases, the API methods may shorten the writing of your code but increase its running time. The only classes and methods you can use are listed below. Note: if a method you want to use from the API is not listed, you should not implement the method yourself so you can use it. Rather, you shoud look for the solution that does not need that method.

  You are allowed to use the following methods from the Java API:

  • class String
    • length
    • charAt
  • class StringBuilder
    • length
    • charAt
    • append
    • toString
  • class Character
    • any method

Create a class called HW2 that contains the following methods:

1. replaceFirstK: takes a String, two chars, and an int as input and returns a String that is the same as the parameter String except that first int occurrences of the first char parameter are replaced with the second char parameter.

   > HW2.replaceFirstK("Mississippi River", 'i', 'I', 3)
   "MIssIssIppi River"
   > HW2.replaceFirstK("Missouri River", 'r', '*', 3)
   "Missou*i Rive*"
   

2. allChars: takes two char parameters. Creates a String containing all characters, in order, from the first char parameter (inclusive) to the last (inclusive).

   > HW2.allChars('d', 'm')
   "defghijklm"
   

3. showCharOfString: takes two String parameters. Outputs a new String that is the same as the first String except that: for each character of the first String, if the character is not in the second String, replace that character with the underscore ('_').

   > HW2.showCharOfString("Missouri River", "s SR!r")
   "__ss__r_ R___r"
   

4. hangman: Takes a String and an int and returns a boolean. The method plays the game of hangman where the String is the word the player must guess and the int is the maximum number of "bad guesses" allowed. The game should work as follows:

   1. Creates a StringBuilder that stores all the letters guessed by the player. The StringBuilder should initially be empty.
   2. Has a loop that does the following:
      1. Calls the showCharOfString on the parameter String and a string containing all the guessed letters.
      2. Uses System.out.println to print the String returned from the previous step as well as the total number of "bad guesses" so far. (For fun, you can print a graphical hangman instead of the number of bad guesses.)
      3. Uses javax.swing.JOptionPane.showInputDialog to get the next guessed letter from the user. The method should not crash if the user does not enter appropriate data.
      4. If the letter has not yet been guessed, adds the letter to the StringBuilder containing the guessed letters and if the letter is not in the input String, increases the count of "bad guesses" by one.
   3. The loop repeats until either: all letters of the parameter String are guessed or the number of "bad guesses" equals the int parameter.
   Finally, the method returns true if the player guessed all the letters of the input String without reaching the limit on "bad guesses", and false if the "bad guesses" limit was reached. You should organize your loop so the return statement is after the loop terminates.

5. hiddenString: takes an array of char and a String as input parameters and and returns an boolean. The method returns true if we can find the input string inside the array by starting at any position of the array and reading either forwards or backwards.

   > HW2.hiddenString(new char[]{'a','b','r','a','c','a','d','a'}, "acad")
   true
   > HW2.hiddenString(new char[]{'a','b','r','a','c','a','d','a'}, "carb")
   true
   > HW2.hiddenString(new char[]{'a','b','r','a','c','a','d','a'}, "brad")
   false
   

6. hiddenString: takes a 2-dimensional array of char and a String as input parameters and returns a boolean. The method returns true if we can find the input string inside the array by starting at any position of the array and reading in any straight direction (up, down, left, right, or diagonal).

   > HW2.hiddenString(new char[][]{{'a', 'b', 'c'},{'r','c','a','d'},{'b','r'}}, "bcc")
   true
   > HW2.hiddenString(new char[][]{{'a', 'b', 'c'},{'r','c','a','d'},{'b','r'}}, "ace")
   false
   > HW2.hiddenString(new char[][]{{'a', 'b', 'c'},{'r','c','a','d'},{'b','r'}}, "cad")
   true
   

7. Extra Credit (up to 10%)capitalizeWords takes a String as input and returns a String as output. Any word in the input string (a word is defined as a sequence of Enlish letters plus the hypen -) that contains any capitalized letter will have all its letters capitalized in the output string.

   > HW2.capitalizeWords("Guess what??  There are twenty-sIx letters in the English alphABEt!")
   "GUESS what??  THERE are TWENTY-SIX letters in the ENGLISH ALPHABET!"

Third Assignment
Please read the following scenario and then refer to the materials of the courseto answer the questions
The scenario:
Dr. Latif is a new nephrologist employee working in the kidney dialysis unit at one of the Palestinian hospitals, and he deals with chronic patients who are visiting the unit "2 or 3" times weekly, so the staff is familiar with the patients and they formulated very close interaction and relationship.
He started to feel overinvolved with one of the patients who has many personal and family conflicts and she used to share it with Dr.Latif as he was very close to her, even they were friends on social media and he consider her to be a close friend, he felt empathetic with her, with time he started to be uncomfortable as the relationship started to cross the professional standers and he became emotional over-involvement.
Answer the following questions
1-Please, differentiate between the levels of patient-"Health care provider" like Doctor, Nurse…etc. involvement?
2-What communication skills should Dr. Latif follow to assure the professional relationship. And why?
3-Why do you think the patient-Doctor/Nurse relationship could become intimate ??reflect from the case
4- Please summarize in two lines how could the nurse be empathic with the patients but keep professional standers?
-You can submit the assignment either group"4-8" or individual work
-Use scientific accurate English language
-Use just Microsoft word document type
-Please do your efforts to express using your own language, don’t just copy and paste from internet sites, if you use reference mention them.

In a business setting, we are often asked to write a memo to communicate with internal and external professionals. To further advance your learning of memo communication, this written case requests that you prepare a memo to communicate within the company.

Background:

As the senior accountant at Technology on Demand (TOD), which manufactures mobile technology such as flip phones, smartphones, notebooks, and smartwatches, you are often asked to prepare various financial analysis necessary for decision making. Michelle Dodd, the controller, asked you to evaluate whether a piece of factory equipment should be replaced or kept. The old piece of factory equipment was purchased four years ago for $875,000. Over the last four years, TOD has allocated depreciation based on the straight-line method. The expected salvage value is $25,000. The current book value of the factory equipment is $425,000. The operating expenses total approximately $45,000 a year. It is estimated that the residual value (market value) of the old machine is $350,000. The controller is contemplating whether to replace the piece of factory equipment. The replacement factory equipment would consist of a purchase price of $500,000, a useful life of eight years, salvage value of 30,000, and annual operating costs of $35,000. In consideration of the background, prepare a memo in a Word document to submit to the controller. Your first paragraph would be an introduction paragraph of what the memo is about. Next, you will want to consider the equipment replacement decision. To add clarity to your discussion, you are to insert a table comparing the old equipment to the new equipment. In evaluating the “relevant” costs, what does your analysis show? Do you recommend that the equipment be replaced or kept ongoing for the next eight years? Why or why not?

Participate in the discussion by providing a point of view with a rationale, challenging an aspect of the discussion, or indicating a relationship between two or more lines of reasoning in the discussion. Complete your participation for this assignment by the due date assigned.

Discussion:

Part One:

Using the directional terms in the table from your textbook, describe how you, or someone close by you, is sitting or standing. Include at least 5 of the terms describing body positioning and movement. Then describe the opposite (for example, if you said your foot was plantar flexed, use dorsiflexed) for all of the terms you used, and make a guess whether you would be comfortable in that position.

Your response should be posted to the Discussion Area below. By the end of the week, begin commenting on at least 2 of your peers' responses. Ask questions, further the discussion of the topic, reinforce a response, or add another dimension to the discussion. Always use constructive language.

Part Two

Think of a few examples or do some research into examples where the prefix or suffix of a root word changes the meaning from one term to another. Why is it critical for medical professionals to understand and use prefixes and suffixes carefully?

Health Insurance and Economy

When dealing with public health policy and laws, we need to consider various aspects of the economy. Concepts of efficiency can be utilized when deciding which goods and services should be produced and who should receive them.

The three types of efficiencies are allocative, production, and technical. The two types of health economics are positive and normative. Positive Economics deals with "what is" or the current status that is linked to a clear standard of measurement. Normative economics deals with "what ought to be" and is subject to interpretation with the moral or ethical aspects of a policy. Your lecture has more details.

Using South University Online Library or the Internet, search the article, “The Interplay of Public Health Law and Industry Self-Regulation: The Case of Sugar-Sweetened Beverage Sales in Schools."

On the basis of the article and your understanding on the topic, write a 3- to 4-page essay in a Microsoft Word document on the three types of economic efficiencies and both positive and normative economics as it relates to regulating sugar-sweetened beverage sales in schools.

Support your statements with at least two other scholarly sources, correctly formatted in APA style. This assignment requires a title page, an introduction, a body, a conclusion, and a separate reference page.

Fact Pattern #1:

Pat contracts with an Ajax Insurance Company agent for a $50,000 ordinary life insurance policy. The application form is filled in to show Pat's age as 32. In addition, the application form asks whether Pat has ever had any heart ailments or problems. Pat answers no, forgetting that as a young child he was diagnosed as having a slight heart murmur. A policy is issued. Three years later, Pat becomes seriously ill and dies. A review of the policy discloses that Pat was actually 33 at the time of the application and the issuance of the policy and that he incorrectly answered the question about the history of heart ailments.

Fact Pattern #2:

Best Insurance Company provides Eve Erickson with property insurance that contains an 80% coinsurance clause. The coinsurance clause states that if Eve insures the property up to 80% of its value, she will recover any loss up to the face amount of the policy. Eve purchases an $80,000 property insurance policy for property valued at $200,000. Due to a fire, Eve suffers a loss of $10,000.

Adapted from Business Law, 114h Edition, by Clarkson, Miller, Jentz and Cross, (2016).

Nonparametric Methods
In this assignment, we will use the following nonparametric methods:

• The Wilcoxon signed-rank test: The Wilcoxon signed-rank test is the nonparametric test analog of the paired t-test.
• The Wilcoxon rank-sum test or the Mann-Whitney U test: The Wilcoxon rank-sum test is an analog to the two-sample t-test for independent samples.

Part 1: Wilcoxon Signed-Rank Test

Let's take a hypothetical situation. The World Health Organization (WHO) wants to investigate whether building irrigation systems in an African region helped reduce the number of new cases of malaria and increased the public health level.

Data was collected for the following variables from ten different cities of Africa:

• The number of new cases of malaria before the irrigation systems were built
• The number of new cases of malaria after the irrigation systems were built

Table 1: Cases of Malaria

Using the Minitab statistical analysis program to enter the data and perform the analysis, complete the following:

• Run a sample Wilcoxon signed-rank test to show whether there is a statistically significant difference between the number of cases before and after the irrigation systems were built.
• Obtain the rank-sum.
• Determine the significance of the difference between the groups.
• Determine whether building these systems helped reduce new cases of malaria.
• In a Microsoft Word document, provide a written interpretation of your results.

1. Dr. Woz and Dr. Yaz want to test whether violent video games have an effect on aggressive thinking. In order to test aggressive thinking, Woz and Yaz are going to use a test developed at GTA University; scores greater than 70 on the test indicate agreement with statements that endorse aggressive behavior. They select a sample of n = 100 teenagers from a local high school for the study. Each of the students spends an hour playing a first-person shooter video game and then takes the test. The mean and standard deviation for the sample is M = 73 and s = 20. Woz and Yaz would like to know if the sample mean of 73 is statistically significantly different from 70 using a two-tailed test with ? < .05 and critical values of t of ±1.98.

a. What is the null hypothesis for this test? H₀ =

b. What is the estimated standard error for this test?

c. Calculate the value of t (round to two decimal places, if rounding is necessary).

d. Do you accept or reject the null hypothesis?

2. A paired samples t-test produces the following results: t(99) = 2.15, p < .05. The study included 1 blank participants and the decision was to 2 blank the null hypothesis. (Note: Your first answer will be a number and your second will be a word.)

3. The estimated standard error:
